Steam enters an adiabatic turbine steadily at 7 500 ℃, and 45 m/ and leaves at 100 and 75 m/ if the power output of the turbine is 5 and the isentropic efficiency is 77 determine:

(a) the mass flow rate of steam through the turbine,
(b) the temperature at the turbine exit, and
(c) the rate of entropy generation during this process

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

The force on a cutting tool are 2600n vertically downward and 2100 horizontal. determine the resultant force acting on the tool and the angle at which it acts.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
