1. An ideal gas with Cp/Cv=1.5 where Cp and Cv are respectively the heat capacities at constant pressure and constant volume, is used as the working substance of a Carnot engine. The temp of the source is 600K and that of the sink is 300K.
The volume of gas changes from 4 to 1 liter at the low temp and the pressure at the volume of 4 liters is one atm.
calculate the volumes and pressures at the extreme points of the high temp expansion.
calculate the heat absorbed there
Calculate the heat given out at the low temp
what is the efficiency ?
2. Two identical bodies of constant heat capacity are initially at temperatures T1 and T2. They are used as the sink and source of a Carnot engine and no other source of heat is available.
Calculate the final, common temperature when all possible work has been extracted from the system.
Calculate the maximum work obtainable.
Experiments have revealed that flow over the board is disturbed by the elements and that convection heat transfer is correlated by an expression of the form Nux = 0.4 Re0.85 Pr 1/3 . Estimate the surface temperature of the chip if it is dissipatin..
One load absorbs 1.5kW at a 0.707 pf lagging. Determine: (a) the pf of the second load, (b) the parallel element required to correct the pf to 0.9 lagging for the two loads.
A three-phase, 2000-kVA, 12-kV, 1800-rpm synchronous generator has a synchronous reactance of 20 ohms per phase and negligible armature resistance.a. The field current is adjusted to obtain the rated terminal voltage at open circuit.
A three-point symmetric moving average filter, referred to as a weighted moving average is of the form \(y[n]=b(ax[nu22121]+x[n]+ax[n+1])\) (a) Determine as a function of a and b the frequency response \(H(e^{j\omega})\) of this system.
A piston-cylinder device initially contains 1 m of nitrogen gas at 400kpa and 27 c. A resistance heater is turned on inside the cylinder which passes 70 kj of electricity to the nitrogen gas.
The shunt capacitance of metal work ofeach insulator is 0.26C to earth and 0.15C to line. Find the stringefficiency if a guard ring increases the shunt capacitance to lineof the metal work of the lowest insulator to 0.35C.
A Si p+-n junction has the following parameters at 300K: taup = taug = 10-6 s, ND=1015 cm-3, and NA=1019 cm-3. Plot diffusion current density, generation current (Jgen) and total reverse current (JR) as a function
