Select the proper traffic pattern and runway for landing.
a). Left-hand traffic and Runway 22.
b). Left-hand traffic and Runway 18.
c). Right-hand traffic and Runway 18.
Answers
The correct answer would be b) Left-hand traffic and Runway 18. When approaching an airport, pilots must follow a specific traffic pattern to ensure safe and efficient arrivals and departures. The traffic pattern direction and runway in use are determined by the wind direction and other factors. In this case, Runway 18 is being used, and left-hand traffic is the appropriate pattern to follow.
This means that all turns in the pattern will be made to the left, and aircraft will enter the pattern from the downwind leg, which is opposite the direction of landing. Left-hand traffic and Runway 22.The choice of traffic pattern and runway for landing is determined by a number of factors such as wind direction, traffic flow, and airport layout. The appropriate selection ensures safe and efficient operations during takeoff and landing.In this case, the correct answer would be a) Left-hand traffic and Runway 22. This means that aircraft approaching the airport would fly a left-hand traffic pattern, which involves making left turns when approaching and departing from the runway.The choice of Runway 22 indicates that the runway direction is oriented at 220 degrees. This is important because it aligns with the direction of the wind and allows aircraft to take off and land into the wind, which provides better performance and control.Option b) Left-hand traffic and Runway 18 would not be the correct choice as the runway is oriented in a different direction than the wind, which could create a crosswind situation, making landing and takeoff more difficult and unsafe.Option c) Right-hand traffic and Runway 18 would also not be the correct choice as it would require aircraft to fly a right-hand traffic pattern, which is less common and may cause confusion or errors in communication between pilots and air traffic controllers.In summary, the appropriate choice of traffic pattern and runway for landing is determined by factors such as wind direction, airport layout, and traffic flow, and selecting the correct combination ensures safe and efficient operations during takeoff and landing.

3. A shaft used for a pump is made of plain-carbon steel 1090 having an ultimate tensile strength of 400 MPa. If it is subjected to a tensile load of 50 kN, determine the safe diameter using a FOS of 2. Why are we using a lower FOS? 4. List the important determinants of column strength.
Answers
The safe diameter of the pump shaft is [insert answer]. Using a lower factor of safety (FOS) ensures structural integrity and accounts for uncertainties and variations.
To determine the safe diameter of the pump shaft, we consider the ultimate tensile strength of the material, which is given as 400 MPa. The tensile load acting on the shaft is specified as 50 kN.
To calculate the safe diameter, we divide the tensile load by the ultimate tensile strength and multiply it by the FOS. The formula for determining the safe diameter is:
Safe diameter = (Load / Ultimate tensile strength) * FOS
Substituting the given values, we have:
Safe diameter = (50,000 N / 400,000,000 N) * 2
After performing the calculation, we find the safe diameter of the pump shaft to be [insert value]. This means that the shaft should have a diameter equal to or greater than this value to ensure it can withstand the applied load with a factor of safety of 2.
Using a factor of safety (FOS) is important because it accounts for uncertainties in material properties, manufacturing processes, and loading conditions. It provides an additional margin of safety by considering the potential for variations and unexpected circumstances that may occur during the lifespan of the shaft.

Assuming the same filter as in Problem No.2 (with the same cake and filter medium) is used for filtration of an aqueous suspension, but desired for working at a constant filtration rate of 200 L/h.
=> What pressure drop (ΔP) would be attained after 45 min from the start ?
Answers
The actual filtration rate (dV/dt) for a time interval of 45 minutes is given by the formula: dV/dt = Q/A = (300 L / 45 min) / A = 6.67 L/min.
How is constant pressure filtration calculated?Constant rate filtration is described by the equation P = av c A 2 (V) d V d t + R m A d V d t. If the average specific resistance and dry cake mass per unit volume of filtrate are constant, i.e. for incompressible filtration, then Eq. (5) should be linear. In Eq. 1, the "filtration constants"
300 L of filtrate were collected after 45 minutes.
The following calculation can be used to calculate the actual filtration rate (dV/dt):
\(dV/dt = A * (dh/dt)\)
(dV/dt) = Q/A
where Q represents the filtrate's volumetric flow rate.
As a result, the real filtration rate (dV/dt) at 45 minutes is:
dV/dt = Q/A = (300 L / 45 min) / A = (6.67 L/min) / A

A sensor produces a signal with amplitude 15 mV. A voltage amplifier must amplify the signal such that the amplitude of the output signal is at least 2 V. What is the minimum voltage gain (in dB) for the amplifier to meet the requirements
Answers
Answer:
42.50 dB
Explanation:
Determine the minimum voltage gain
amplitude of input signal ( Vi ) = 15 mV
amplitude of output signal ( Vo) = 2 V
Vo = 2 v
therefore ; minimum gain = Vo / Vi = 2 / ( 15 * 10^-3 )

Why is light important to our laying chickens?
Answers
Explanation:
Understanding the significance of lighting in the production of poultry requires an examination of the biological makeup of the birds. In people, light travels from the eyes to the brain. Light enters chickens' bodies through their eyes as well as the top of the skull, their pineal gland, and their pituitary gland near their hypothalamus. Chickens have four varieties of cones, including red, blue, green, and an ultraviolet light cone, compared to human eyes' three types of cones, which are specialized photoreceptor cells that are responsible for how we perceive red, blue, and green light.
Similar to humans, chickens follow a regular cycle of day and night. Birds who have a regular cycle of day and night also have regular diurnal rhythms or a schedule of normal daily activity. For processes like the generation of melatonin, this is crucial. According to Schwean-Lardner, "It is a regular cycle that is very crucial for birds because it governs things like immune function, development rate, and reproductive hormones."

Note that the lighting load on a 120v circuit for six 100w incandescent lights and four fluorescent fixtures with a ballast rating of 1.5a, all operating continuously for 8 hours per day is: 10,560 Watts.
What is Lighting Load?A building's lighting loads are sometimes referred to in terms of "Lighting Power Density," which is measured in watts per square foot or square meter.
It is to be noted that a single calculation is used to compute lighting load:
W=VA.
Where
W = Watts
V = Volts; and
A = Amps
To determine the total wattage for the fluorescent fixtures we say:
4 fixtures x 1.5 amps x 120 volts = 720 watts
Next, we add the wattages for the incandescent lights and fluorescent fixtures to get the total wattage for the circuit. That is:
(6 x 100watts) + 720 watts
= 600 watts + 720 watts
= 1,320 watts
Thus the Load is 1,320 watts.
If all lighting will operate continuously for 8 hours/day, then:
Daily energy consumption will be:
1320 x 8
= 10,560 Watts.
Thus, the Lighting Load on a 120v circuit for 6 100w incandescent lights and four fluorescent fixtures with a ballast rating of 1.5a Operating at 8 hours per day is 10,560 Watts.

incompressible steady flow in the inlet between parallel
plates in Fig. P3.17 is uniform, u U0 8 cm/s, while
downstream the flow develops into the parabolic laminar
profile u az(z0 z), where a is a constant. If z0 4 cm
and the fluid is SAE 30 oil at 20°C, what is the value of
u
max in cm/s?
Answers
The maximum velocity (u_max) in the parabolic laminar flow is 12 cm/s.
How to solveIn the problem statement, it is given that the incompressible steady flow is uniform with u = U0 = 8 cm/s in the inlet.
Downstream, the flow develops into a parabolic laminar profile with u = az(z0 - z). The fluid is SAE 30 oil at 20°C, and z0 = 4 cm.
First, we need to find the dynamic viscosity of SAE 30 oil at 20°C. SAE 30 oil has a kinematic viscosity (ν) of approximately 300 cSt (centistokes) at 20°C.
To convert this to dynamic viscosity (μ), we need to multiply by the density (ρ) of the oil:
μ = ν * ρ
The density of SAE 30 oil is approximately 0.89 g/cm³ (890 kg/m³). Since 1 cSt is equal to 1 × 10⁻⁶ m²/s, the kinematic viscosity in SI units is 300 × 10⁻⁶ m²/s.
Now, let's convert the density to SI units:
ρ = 890 kg/m³ = 0.89 g/cm³
Thus, the dynamic viscosity (μ) can be calculated as follows:
μ = (300 × 10⁻⁶ m²/s) * (890 kg/m³) = 0.267 kg/(m*s)
Now, we need to find the maximum velocity (u_max) in the parabolic laminar flow, which occurs at the center of the plates (z = z0/2):
u_max = a * z0/2 * (z0 - z0/2)
Since the flow is incompressible, the mass flow rate (Q) remains constant throughout. We can equate the mass flow rate at the uniform flow (Q_inlet) with the mass flow rate at the parabolic flow (Q_parabolic):
Q_inlet = Q_parabolic
ρ * U0 * A_inlet = ∫[ρ * a * z * (z0 - z) * A_parabolic] dz
The area A_inlet and A_parabolic both can be represented as A = b * z, where b is the width of the parallel plates, and z is the distance between the plates.
Therefore, the equation simplifies to:
U0 * b * z0 = ∫[a * z * (z0 - z) * b] dz, with integration limits 0 to z0
U0 * z0 = ∫[a * z * (z0 - z)] dz, with integration limits 0 to z0
8 cm/s * 4 cm = a * ∫[z * (4 cm - z)] dz, with integration limits 0 to 4 cm
32 cm²/s = a * ∫[4z - z²] dz, with integration limits 0 to 4 cm
Now we can integrate and apply the limits:
32 cm²/s = a * [2z² - (1/3)z³] | (0 to 4 cm)
32 cm²/s = a * [(2 * 4² - (1/3) * 4³) - 0]
32 cm²/s = a * (32 - 64/3)
32 cm²/s = a * (32 - 21.33)
32 cm²/s = a * 10.67 cm²
Now we can solve for 'a':
a = 32 cm²/s / 10.67 cm² = 3 cm/s
Finally, we can find the maximum velocity (u_max) at the center of the plates
Now that we have the value of 'a' (3 cm/s), we can find the maximum velocity (u_max) at the center of the plates (z = z0/2):
u_max = a * z0/2 * (z0 - z0/2)
u_max = 3 cm/s * (4 cm)/2 * (4 cm - 4 cm/2)
u_max = 3 cm/s * 2 cm * 2 cm
u_max = 12 cm/s
Thus, the maximum velocity (u_max) in the parabolic laminar flow is 12 cm/s.

About what thickness of aluminum is needed to stop a beam of (a) 2.5-MeV electrons, (b) 2.5-MeV protons, and (c) 10-MeV alpha particles?
Answers
The thickness of aluminium needed to stop the beam electrons, protons and alpha particles at the given dfferent kinetic energies is 1.5 x 10⁻¹⁴ m.
Thickness of the aluminum
The thickness of the aluminum can be determined using from distance of closest approach of the particle.
\(K.E = \frac{2KZe^2}{r}\)
where;
Z is the atomic number of aluminium = 13e is charge r is distance of closest approach = thickness of aluminiumk is Coulomb's constant = 9 x 10⁹ Nm²/C²For 2.5 MeV electrons\(r = \frac{2KZe^2}{K.E} \\\\r = \frac{2 \times 9\times 10^9 \times 13\times (1.6\times 10^{-19})^2}{2.5 \times 10^6 \times 1.6 \times 10^{-19}} \\\\r = 1.5 \times 10^{-14} \ m\)
For 2.5 MeV protonsSince the magnitude of charge of electron and proton is the same, at equal kinetic energy, the thickness will be same. r = 1.5 x 10⁻¹⁴ m.
For 10 MeV alpha-particlesCharge of alpah particle = 2e
\(r = \frac{2KZe^2}{K.E} \\\\r = \frac{2 \times 9\times 10^9 \times 13\times (2 \times 1.6\times 10^{-19})^2}{10 \times 10^6 \times 1.6 \times 10^{-19}} \\\\r = 1.5 \times 10^{-14} \ m\)
Thus, the thickness of aluminium needed to stop the beam electrons, protons and alpha particles at the given dfferent kinetic energies is 1.5 x 10⁻¹⁴ m.

a mold cavity has the shape of a cube, 100 mm on a side. determine the volume and dimensions of the final cube after cooling to room temperature if the cast metal is copper.
Answers
The final cube will have a volume of 1,000,003.4 cubic mm and dimensions of 100.00034 mm on a side in a cast metal.
What is cast metal?Static friction is an opposing force that resists the motion of two surfaces in contact with each other. It acts parallel to the surfaces and opposes their relative motion. Static friction is always less than the maximum frictional force, known as the limiting friction, and is often modeled as a coefficient of friction.
The coefficient of thermal expansion of copper is 0.000017/°C. This means that for every 1°C increase in temperature, the copper will expand by 0.000017. Assuming that the room temperature is 20°C, the final cube will have dimensions of 100.00034 mm on a side and a volume of 1,000,003.4 cubic mm. Therefore, the final cube will have a volume of 1,000,003.4 cubic mm and dimensions of 100.00034 mm on a side.
