ii) Find the reactive power supplied by the source and draw the power triangle showing all power components.
iii) Determine the type and value of component required to be placed in parallel with the source to improve the power factor to 0.9 leading.
Answers
The following are the solution of the given problem:i) The Thevenin equivalent circuit for the network shown in Figure 1, looking into the circuit from the load terminals AB is shown below:Given the resistor R4, is short-circuited because there is no current flowing through it since the load RL is connected across it.
To find V_th, we can use the voltage divider formula:V_th = V1 * R2 / (R1 + R2)Where V1 = 20V, R1 = 30Ω, R2 = 60ΩTherefore, V_th = (20 * 60) / (30 + 60) = 12VTo find R_th, we need to find the equivalent resistance looking into the terminals AB.To do that, we can short-circuit the voltage source and find the total resistance:R_th = R1 || R2 || R3 + R4Where || denotes the parallel combination of the resistors.R_th = [(R1 || R2) + R3] || R4Where R1 || R2 = (R1 * R2) / (R1 + R2) = 20ΩSo,R_th = (20 + 30) || 60 = 50Ω.
So, Thevenin equivalent circuit will be:ii) The maximum power transferred to the load can be found by calculating the load resistor value which gives maximum power transfer. Since, RL is varying the maximum power transferred occurs when RL is equal to R_th.
Therefore the maximum power transferred to the load is:Pmax = V_th^2 / (4 * R_th) = 12^2 / (4 * 50) = 0.72 Wb) i) Power factor can be calculated by using the formula:Power factor = Cos Φ = P / SWhere P is the real power, S is the apparent power and Φ is the phase angle.
P = V * I * Cos ΦWhere V = 120 VAC, I = 14.7 A, P = 1 kW.Cos Φ = P / (V * I) = 1000 / (120 * 14.7) = 0.57Power factor = 0.57ii) Reactive power can be calculated by using the formula:Reactive power = Sqrt(Q^2 - P^2)Where Q is the apparent power.
Q = V * I = 120 * 14.7 = 1764 VARReactive power = Sqrt(1764^2 - 1000^2) = 1311.52 VARPower triangle showing all power components:iii) To improve the power factor to 0.9 leading, a capacitor should be placed in parallel with the source. The type of the component should be a capacitor because the load is an inductive load.
To calculate the capacitance required, we can use the formula:Capacitance = (Q * Tan Φ2) / (2 * π * V^2).Where Φ2 is the angle between the supply voltage and the supply current when the power factor is 0.9 leading.
Since, the angle is leading, Φ2 will be negative.Φ2 = - Cos^-1 0.9 = - 25.84°Capacitance = (1311.52 * Tan -25.84) / (2 * π * 120^2) = 0.0089 FSo, the component required is a capacitor of capacitance 8.9 mF (millifarads).

a cubical box 20-cm on a side is contructed from 1.2 cm thick concrete panels. A 100-W light bulb is sealed inside the box. What is the temperature on teh inside ofthe box when the light is on and the outside temperature is 20C
Answers
Answer:
Temperature on the inside ofthe box
Explanation:
The power of the light bulb is the rate of heat conduction of the bulb, \(dq/dt = 100 W\)
The thickness of the wall, L = 1.2 cm = 0.012m
Length of the cube's side, x = 20cm = 0.2 m
The area of the cubical box, A = 6x²
A = 6 * 0.2² = 6 * 0.04
A = 0.24 m²
Temperature of the surrounding, \(T_0 = 20^0 C = 273 + 20 = 293 K\)
Temperature of the inside of the box, \(T_{in} = ?\)
Coefficient of thermal conductivity, k = 0.8 W/m-K
The formula for the rate of heat conduction is given by:
\(dq/dt = \frac{kA(T_{in} - T_0)}{L} \\\\100 = \frac{0.8*0.24(T_{in} - 293)}{0.012}\\\\T_{in} - 293 = \frac{100 * 0.012}{0.8*0.24} \\\\T_{in} - 293 = 6.25\\\\T_{in} = 293 + 6.25\\\\T_{in} = 299.25 K\\\\T_{in} = 299.25 - 273\\\\T_{in} = 26.25^0 C\)

P9.28 A large vacuum tank, held at 60 kPa absolute, sucks sea- level standard air through a converging nozzle whose throat diameter is 3 cm. Estimate (a) the mass flow rate through the nozzle and (b) the Mach number at the throat.
Answers
Answer:
a) \(m=0.17kg/s\)
b) \(Ma=0.89\)
Explanation:
From the question we are told that:
Pressure \(P=60kPa\)
Diameter \(d=3cm\)
Generally at sea level
\(T_0=288k\\\\\rho_0=1.225kg/m^3\\\\P_0=101350Pa\\\\r=1.4\)
Generally the Power series equation for Mach number is mathematically given by
\(\frac{p_0}{p}=(1+\frac{r-1}{2}Ma^2)^{\frac{r}{r-1}}\)
\(\frac{101350}{60*10^3}=(1+\frac{1.4-1}{2}Ma^2)^{\frac{1.4}{1.4-1}}\)
\(Ma=0.89\)
Therefore
Mass flow rate
\(\frac{\rho_0}{\rho}=(1+\frac{1.4-1}{2}(0.89)^2)^{\frac{1.4}{1.4-1}}\)
\(\frac{1.225}{\rho}=(1+\frac{1.4-1}{2}(0.89)^2)^{\frac{1.4}{1.4-1}}\)
\(\rho=0.848kg/m^3\)
Generally the equation for Velocity at throat is mathematically given by
\(V=Ma(r*T_0\sqrt{T_e}\))
Where
\(T_e=\frac{P_e}{R\rho}\\\\T_e=\frac{60*10^6}{288*0.842\rho}\)
\(T_e=248\)
Therefore
\(V=0.89(1.4*288\sqrt{248})\\\\V=284\)
Generally the equation for Mass flow rate is mathematically given by
\(m=\rho*A*V\)
\(m=0.84*\frac{\pi}{4}*3*10^{-2}*284\)
\(m=0.17kg/s\)

Answers
The correct statements are 2, 3 and 5. Elastic deformation is a temporary deformation of a material. When a force is applied to a material, it will deform, and the amount of deformation will be proportional to the force applied.
Elastic deformation refers to the reversible deformation of a material when a force is applied and it is released. When the load is removed, the material will return to its original shape. Elastic deformation is characterized by its capability to withstand stress without causing any permanent change in the shape of the material or its molecular structure. The following are the correct statements regarding elastic deformation: Stress and strain are proportional; hence, when stress is applied, the deformation or strain is proportional to the stress. Isostatic uplift following deglaciation represents elastic deformation. This statement is correct. Fold structures are the result of elastic deformation. This statement is correct.
Therefore, If the force is removed, the material will return to its original state. The explanation for elastic deformation is that the stress and strain are proportional, and the deformation will not cause any permanent change in the shape or molecular structure of the material.

A branch circuit supplies electricity to the appliances in your house or company, such as lighting, air conditioning, and outlets, from your home's or office's electrical panel. Because there are a variety of appliances in a home, the circuit's current-carrying capacity should be adequate to handle the anticipated current that will be required.
The principle of "load balancing" is used in commercial electrical design. The objective is to distribute power among various circuits and branches evenly. In addition, individual branch circuits are equipped with a means of disconnecting or isolating the circuit's load from the primary source, such as a circuit breaker. This isolation or de-energizing of a branch circuit is critical when maintaining or working on electrical equipment.

The big ben clock tower in London has clocks on all four sides. If each clock has a minute hand that is 11.5 feet in length, how far does the tip of each hand travel in 52 minutes?
The distance traveled by the tip of the minute hand of the clock would be 62.59 ft
Explanation:
Let us assume the shape of the clock is circular.
the minute hand is equal to the radius = 11.5 ft
Diameter = radius x 2
Diameter = 11.5 x 2 = 23 ft
The distance traveled by the tip of the minute hand can be calculated thus;
the fraction of the circumference traveled by the minute hand would be;
52/60 = 0.8667
Circumference of the clock would be;
C = pi x d
where C is the circumference
pi is a constant
d is the diameter
C = 3.14 x 23
C = 72.22 ft
Therefore the fraction of the circumference covered by the minute hand would be;
72.22 ft x 0.8667 = 62.59 ft
Therefore the distance traveled by the tip of the minute hand of the clock would be 62.59 ft

nd demo of reaper in Mahindra Yuvo 575 DI tractor
Answers
Answer:
Explanation:
It appears that you are trying to solve a problem involving an insulated rigid tank containing saturated liquid water and water vapor. To determine the volume of the tank, you will need to know the mass of the liquid water and the mass of the water vapor. The mass of the liquid water can be calculated by multiplying the mass of the water and vapor mixture by the fraction of the mixture that is liquid water (1.4 kg * 0.25 = 0.35 kg). The mass of the water vapor can be calculated by subtracting the mass of the liquid water from the total mass of the mixture (1.4 kg - 0.35 kg = 1.05 kg).
To determine the final temperature of the tank, you will need to know the amount of heat added to the tank by the electric resistor and the specific heat capacity of the water and water vapor mixture. The specific heat capacity is a measure of the amount of heat required to raise the temperature of a substance by a certain amount. The specific heat capacity of water is 4.186 J/g°C, and the specific heat capacity of water vapor is 2.080 J/g°C.
To determine the electric power rating of the resistor, you will need to know the amount of heat added to the tank by the resistor and the time over which the heat was added. The power rating of the resistor is equal to the amount of heat added to the tank divided by the time over which the heat was added.
