#10. Consider the piston cylinder and tank shown. The piston cylinder contains 0.0102kg of air at 420K and 101kPa.
The air is compressed to 390K and 158kPa. Heat is generated by the compression of the air and is transferred to a
closed rigid tank. The tank initially contains 0.01m^(3) of water at 100deg C and a quality of 80%. The heat is transferred to
the tank until the pressure is 400kPa. Determine (a) the total mass of the tank (b) the temperature at state 2 of the
tank (c) define the tank as the system and find the heat transferred to the tank, in kJ (d) draw the process on P-v
diagram (e)now define the system as the piston cylinder and determine the work input to compress the gas, in kJ
