One of the cylinder's content is under pressure at 1900 psi (per the gauge) at 70°F. As the day heats up because of the sun, the temperature increases to 105°F. What is the pressure at 105°F?
Answers
The pressure would be doubled (3800psi) as the day heats up because of the sun, the temperature increases to 105°F.
What is relationship between pressure and temperature?If the temperature is on the kelvin scale, then P and T are directly proportional (again, when volume and moles of gas are held constant); if the temperature on the kelvin scale increases by a certain factor, the gas pressure increases by the same factor. We find that temperature and pressure are linearly related.Examine the connection between a gas's temperature and the pressure it applies to its container. This is generally known as Gay-Law Lussac's or Amontons' Law of Pressure-Temperature. A gas will exert greater pressure on its container as its temperature rises.As the temperature rises, the pressure must as well since pressure is the force the particles per unit of area exert on the container.

Ew Wakefield Hospital has only one portable X-ray machine. The emergency room staff claim to have the greatest need for the machine, but the surgeons in the operating room demand ready access to the machine. The conflict between these two groups is a result of scarcity.
Science and technology are the driving forces behind today's modern medicine, allowing us to identify and treat a range of medical problems. X-ray technology has had a significant impact on medicine, and it is commonly used to diagnose various diseases, making it an essential tool for hospitals.
Despite the advantages, the scarcity of portable X-ray machines creates difficulties for hospital employees, including a dispute between the emergency room and the operating room staff at Ew Wakefield Hospital. There is only one portable X-ray machine available at Ew Wakefield Hospital.
The conflict between the emergency room and the operating room staff is a result of scarcity. Both departments require ready access to the X-ray machine. Scarcity can generate rivalry, competition, and conflict when people and organizations compete for the same resource.
The staff's conflict is a direct result of the lack of accessibility to the X-ray machine. Thus, scarcity can be a significant factor contributing to interpersonal conflict.

Briefly explain what is meant by a subcritical refrigeration cycle, and list its four process.
Answers
A subcritical refrigeration cycle is a type of refrigeration cycle that operates below the critical point of the refrigerant. The critical point is the temperature and pressure at which the refrigerant transitions between the liquid and gas phases without any distinction between them.
In a subcritical cycle, the refrigerant remains in the liquid phase during the entire cycle.
The four processes involved in a subcritical refrigeration cycle are:
Compression: The refrigerant enters the compressor as a low-pressure vapor and is compressed to a higher pressure and temperature.
Condensation: The compressed refrigerant flows into the condenser, where it releases heat to the surroundings and changes from a high-pressure vapor to a high-pressure liquid.
Expansion: The high-pressure liquid refrigerant enters the expansion valve or throttle valve, where its pressure is reduced, causing it to partially vaporize and cool.
Evaporation: The partially vaporized refrigerant flows into the evaporator, where it absorbs heat from the surrounding environment, completing the cooling process. The refrigerant then returns to the compressor to start the cycle again.
In a subcritical refrigeration cycle, the cooling effect is achieved through the evaporation of the refrigerant in the evaporator, while the condenser rejects heat to the surroundings.

What signal propagation phenomena causes the diffusion, or the reflection in multiple different directions, of a signal?
Answers
In the radio communication system, multipath is the propagation phenomenon that causes diffusion or reflection in multiple different directions of a signal.
Multipath is a propagation mechanism that impacts the propagation of signals in radio communication. Multipath results in the transmission of data to the receiving antenna by two or more paths. Diffusion and reflection are the causes that create multiple paths for the signal to be delivered.
Diffraction occurs when a signal bends around sharp corners; while reflection occurs when a signal impinges on a smooth object. When a signal is received through more than one path because of the diffraction or reflection, it creates phase shifting and interference of the signal.

b. the back work ratio
c. the net power developed, in kW
d. the rates of exergy destruction in each compressor stage and the turbine stage as well as the regenerator, in kW, for T 0 = 300 K.
Answers
Answer:
a. \(\eta _{th}\) = 77.65%
b. bwr = 6.5%
c. 3538.986 kW
d. -163.169 kJ
Explanation:
a. The given property are;
P₂/P₁ = 10, P₂ = 10 * 100 kPa = 1000 kPa
p₄/p₁ = 10
P₂/P₁ = p₄/p₃ = √10
p₂ = 100·√10
\(T_{2s}\) = T₁×(√10)^(0.4/1.4) = 300 × (√10)^(0.4/1.4) = 416.85 K
T₂ = T₁ + (\(T_{2s}\) - T₁)/\(\eta _c\) = 300 + (416.85 - 300)/0.8 = 446.0625 K
p₄ = 10×p₁ = 10×100 = 1000 kPa
p₄/p₃ = √10 =
p₃ = 100·√10
T₃ = 300 K
T₃/\(T_{4s}\) = (P₂/P₁)^((k - 1)/k) = (√10)^(0.4/1.4)
\(T_{4s}\) = T₃/((√10)^(0.4/1.4) ) = 300/((√10)^(0.4/1.4)) = 215.905 K
T₄ = T₃ + (\(T_{4s}\) - T₃)/\(\eta _c\) = 300 + (215.905- 300)/0.8 = 194.881 K
The efficiency = 1 - (T₄ - T₁)/(T₃ - T₂) = 1 - (194.881 -300)/(300 -446.0625 ) = 0.28
T₄ = 446.0625 K
T₆ = 1400 K
\(T_{7s}\)/T₆ = (1/√10)^(0.4/1.4)
\(T_{7s}\) = 1400×(1/√10)^(0.4/1.4) = 1007.6 K
T₇ = T₆ - \(\eta _t\)(T₆ - \(T_{7s}\)) = 1400 - 0.8*(1400 - 1007.6) = 1086.08 K
T₈ = 1400 K
T₉ = 1086.08 K
T₅ = T₄ + \(\epsilon _{regen}\)(T₉ - T₄) = 446.0625 +0.8*(1086.08 - 446.0625) = 958.0765 K
\(\eta _{th}\) =(((T₆ - T₇) + (T₈ - T₉)) -((T₂ - T₁) + (T₄ - T₃)))/((T₆ - T₅) + (T₈ - T₇))
(((1400 - 1086.08) + (1400 -1086.08 ))-((446.0625 - 300)+(194.881 - 300)))/((1400 -958.0765 ) + (1400 -1086.08 )) = 0.7765
\(\eta _{th}\) = 77.65%
b. Back work ratio, bwr = \(bwr = \dfrac{w_{c,in}}{w_{t,out}}\)
((446.0625 - 300)+(194.881 - 300))/((1400 - 1086.08) + (1400 -1086.08 ))
40.9435/627.84 = 6.5%
c. \(w_{net, out} = c_p[(T_6 -T_7) + (T_8 - T_9)] - [(T_2 - T_1) + (T_4 -T_3)]\)

Answer:
a). \($0.0436 \ ft^3/s$\) , \($2.72 \ lb \ m/s$\)
b). \($61.32 \ s$\)
c). 32. ft/s
Explanation:
a). The volume flow rate of the water is given by :
\($\dot V = uA$\)
\($=u \pi \left( \frac{d}{2}\right)^2$\)
\($=\frac{u \pi d^2}{4}$\)
\($=\frac{8\ ft/s \ \pi \left(\frac{1}{12}\right)^2}{4}$\)
\($= 0.0436 \ ft^3/s$\)
The mass flow rate of the water is given by :
\($\dot m = \rho \dot V$\)
\($= 62.4 \times 0.0436$\)
\($=2.72 \ lb \ m/s$\)
b). The time taken to fill the container is
\($\Delta t = \frac{V}{\dot V}$\)
\($=\frac{20 \ gal}{0.0436 \ ft^3/s}\left( \frac{1 \ ft^3}{7.4804 \ gal}\right)$\)
\($=61.32 \ s$\)
c). The average velocity at the nozzle is :
\($u=\frac{\dot V}{A}$\)
\($=\frac{\dot V}{\frac{\pi d^2}{4}}$\)
\($=\frac{0.0436}{\frac{\pi \left(\frac{0.5}{12}\right)^2}{4}}$\)
= 32. ft/s

Tech B says to use a compression fitting to repair a section of brake line. Who is correct? Tech A Tech A Tech B Tech B Both Both Neither
Answers
Answer:
Tech A is correct.
Explanation:
A front-wheel-drive pulling to the left can result from several factors. One of them is definitely a faulty break.
A correct diagnosis linking the problem to the brakes is when there is an internal restriction and the pull is constant to one side and gets worse when the brakes are applied.
To confirm this, one would need to lift the vehicle and rotate each wheel by hand to check for excessive friction.
So the restriction may be caused by:

A parallel helical gearset consists of a 19-tooth pinion driving a 57-tooth gear. The pinion has a left-hand helix angle of 30°, a normal pressure angle of 20°, and a normal module of 2.5 mm.
Find:_______.
(a) The normal, transverse, and axial circular pitches
(b) The transverse diametral pitch and the transverse pressure angle
(c) The addendum, dedendum, and pitch diameter of each gear
Answers
Answer:
a)
normal circular pitch = 7.8539 mm
transverse circular pitch = 9.0689 mm
axial circular pitches = 15.7077
b)
transverse diametral pitch is 0.3464 teeth/mm
transverse pressure angle is 22.8°
c)
Addendum = 2.5 mm
dedendum = 3.125 mm
pinion diameter = 54.8482 mm and Gear diameter = 164.5448 mm
Explanation:
Given that;
module m = 2.5 mm
Number of teeth on Gear nG = 57 TEETH
Number of teeth on Pinion nP = 19 TEETH
Helix angle W = 30°
Normal Pressure angle β = 20°
finding the circular pitch
Pc = πm
we substitute
Pc = π * 2.5 mm = 7.8539 mm
now the diametral pitch p = π / Pc
= π / 7.8539
= 0.4 teeth/mm
a)
So the normal circular pitch
Pn = π / P
Pn = π / 0.4
Pn = 7.8539 mm
the transverse circular pitch
Pt = Pn / cosW
Pt = 7.8539 / cos30°
Pt = 9.0689 mm
for axial circular pitches
Px = Pt / tanW
Px = 9.0689 / tan30°
Px = 15.7077
b)
The transverse diametral pitch and the transverse pressure angle.
The transverse diametral pitch Pt = PcosW
= 0.4 * cos30°
= 0.3464 teeth/mm
transverse diametral pitch is 0.3464 teeth/mm
transverse pressure angle β1 = tan^-1 ( tan βn / cos W)
= tan^-1 ( tan20° / cos 30°)
= tan^-1 ( 0.42027 )
β1 = 22.8°
transverse pressure angle is 22.8°
c)
The addendum, dedendum, and pitch diameter of each gear
Now from table standard Tooth proportions for Helical Gears;
Addendum a = 1/p
= 1 / 0.4
= 2.5 mm
dedendum b = 1.25 / p
= 1.25 / 0.4
= 3.125 mm
now pinion diameter dP = Np / PcosW
= 19 / 0.4 (cos30°)
= 54.8482 mm
Gear diameter dG = nG / pcosW
= 57 / 0.4 (cos30°)
= 164.5448 mm

Answers
Answer:
698.3KpaExplanation:
Step one:
given data
V1=0.25m^3
T1=290k
P1=100kPa
V2=0.5m^2
T2=405k
P2=? final pressure
Step two:
The combined gas equation is given as
P1V1/T1=P2V2/T2
Substituting we have
(100*0.25)/290=P2*0.05/405
25/290=0.5P2/405
0.086=0.05P2/405
cross multiply
