Chapter 8, Problem 8.29P

Thermodynamics sketch and label the turbine. Sketch and label the process on a T-s diagram also mentions all numbers on the process please. Thanks 7.56 A steam turbine has an inlet of 2 kg/s water at 1000 kPa, 400°C with velocity of 15 m/s. The exit is at 100 kPa, 150°C and very low velocity. Find the power produced and the rate of entropy generation.

one kg of air is compressed in a cylinder according to the law PV^1.3= constant. If intital temperature is 100°C amd compression ratio is 15, find the work done and change in entropy of air.

Steam to a turbine at a mass flow rate of 1.4 kg/s, 700 kPa pressure and 400 °C enters the temperature. Steam at 100 kPa pressure and 1.4 m3/kg specific volume exits the turbine. Heat transfer from turbine to environment 50 kW, with turbine Since the boundary temperature between the environment is 70 °C, a) Find the power produced by the turbine, entropy produced in the turbine and isentropic efficiency of the turbine. Note: The changes in kinetic and potential energies will be neglected and T (K) = 273 + °C will be taken.

A steam is expanded through a nozzle and the enthalphy drop per kg of steam from the initial pressure to the final pressure is 70 kJ. Neglecting the friction, find the velocity of discharge.

The turbine section in a jet engine receives gas (assume air) at 1200 K, 800 kPa with an ambient atmosphere at 80 kPa. The turbine is followed by a nozzle open to the atmosphere and all the turbine work drives a compressor receiving air at 85 kPa, 270 K with the same flow rate. Find the turbine exit pressure P₂ so the nozzle has an exit velocity of 800 m/s.

A factory generates compressed air from 100 kPa, 17°C by compression to 800 kPa, 500 K, after which it cools in a constant pressure cooler to 300 K, (see Fig. P4.36). Find the specific compressor work and the specific heat transfer in the cooler. 1 2 3 Compressor -w. Compressor section Cooler section

· A closed gaseous system undergoes a reversible process with constant pressure of 200kpa. 2500 kJ of heat is rejected, and the volume changes from 5m3 to 2m3. Find the change in internal energy

There are required 2000 kW of compressor power to handle air adiabaticallyfrom 1 atmosphere, 27 oC, to 305 kPaa. The initial air velocity is 20 m/s and the finalvelocity is 85 m/s. a) If the compression is isentropic, find the compressor capacity, inm3/s. b) If the compression process is irreversible adiabatic to a temperature of 160 oC,with the capacity found in c), determine the compressor power input, in Hp.

Please be very detailed
