Steam enters an adiabatic turbine with a mass flow rate of 5 kg/s at 3 MPa, 600° C, and 80 m/s. It exits the turbine at 40°C, 30 m/s, and a quality of 0.9.

Propane initially at 300 K and 100 kPa is is compressed to 1 MPa in a reversible, steady-flow, and compressor. Determine the amount of work in kJ/kg if the process is polytropic with n=1.1. Round your answer to one decimal place

Draw Pv and Ts diagram of reversible isentropic process. Write the relationship betweenthermodynamic properties.   clear writing please

Argon (3 kg) is compressed adiabatically in a piston-cylinder device from 0.41 m3, 0.1 MPa and 27 deg C to 0.08 m3 and 200 deg C. What is the final pressure (kPa) when the process is reversible? (Report answer to two decimal places)
