Turbo machines . I need the solution quickly please

A piston and cylinder machine containing a fluid system has a stirring device in the cylinder. The piston is frictionless and is held down against the fluid due to the atmospheric pressure of 101.325KPa. The stirring device is turned 10000 revolutions with an average torque against the fluid of 1.275mN. Meanwhile the piston of 0.6m diameter moves out of 0.8m. Find the net work transfer for the system.

A fluid undergoes a non-flow frictionless process. Work is -156.2kJ. if V1=0.845m3 and the pressure varies as -730V + 700 kPa where volume is in m3. Find the final volume

Find an expression for the rate of change of the mass of water in the tank.

The power of a steam turbine in a thermal power plant is 60 MW. Water vapor enters the turbine at 3MPa pressure, 4000C temperature and 50 m / s speed, 10 kPa pressure, 0.9 dry degree and 200 m / s speed leaves the turbine. Considering the turbine as adiabatic; 1-Find the mass flow of steam 2-Find the turbine outlet cross-sectional area, its ratio (A2 / A1) to the inlet cross-sectional area.

Find the work posses for a carbon dioxide gas at 1,995.59 C in kJ/kg. (Use W = mRT)
