4-2 ELECTIVE-A (40p) A cylinder fitted with a piston initially has a volume of 0.1 m and contains 0.5 kg of mixture of liquid water and vapor at 0.4 MPa. Heat is transferred to the mixture until the temperature is 300C, while the pressure remains constant. Using the 1st law of Thermodynamics for closed systems, determine a) (10p) quality of the mixture in state 1, in percentage b) (10p) heat addition necessary for the process, kJ c) (10p) work done on the piston during the process, kJ d) (10p) internal energy change of the water during the process, kJ P=0.4 MPa Heat 4-2 ELECTIVE-A (40p) A cylinder fitted with a piston initially has a volume of 0.1 m and contains 0.5 kg of mixture of liquid water and vapor at 0.4 MPa.
