Steam expands in a turbine from 6 mpa, 500°c and 80 m/s to 0.2 mpa, 150°c and 140 m/s at a rate of 1.2 kg/s. heat is lost from the turbine at a rate of 34 kj/s during the process. what is the power output of the turbine? neglect potential energy change g/s

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

On a average work day more than work place firs are reorted

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false
