Chapter 7, Problem 7.35P

A steam turbine has an inlet of 2 kg/s water at 1000 kPa, 350°C and velocity of 15 m/s. The exit is at 100 kPa, x = 1 and very low velocity. Find the specific work and the power produced.

An adiabatic turbine has an efficiency of 90%. If air is compressed from 1100kpa and 227 degree Celsius to 101kpa. Find the work done and final temperature. Sketch process on T-S diagram.

Steam expands isentropically from 2 MPa and 375 o C to a final temperature of 95 o C.Find the final quality and the work for a non-flow and steady flow processes.

Solve it correctly and fast please.

An amount of 4000 BTU of heat is transferred from a reservoir at 800 deg. F to a reservoir at 200 deg. F. Find the entropy change of the system.

Q2) A piston/cylinder has ammonia at 1600 kPa, 100°C with a volume of 0.1 m3. The piston is loaded with a linear spring and outside ambient is at 20 °C. The ammonia now cools down to 10 °C at which point it has a quality of 10%. Find the work, the heat transfer and the total entropy generation in the process. NH₂

9. An air compressor takes in air at 105 Pa and 27°C having volume of 1.5 m3/kg and compresses it to 4.5×105 Pa. Find the work done, heat transfer and change in internal energy if the compression is isothermal.

steam at 11 MPa has a specific volume of 0.0196 m^3/kg , find the temperature, the enthalpy, and the internal energy.
