what is the enthalpy change needed to change 3 kg of liquid water at 0 C to steam at 0.1 MPa and 150 C? B.) What is the enthalpy change needed to heat 3 kg of water from 0.4 MPa and 0 C to steam at 0.1 MPa and 150 C? C.) What is the enthalpy change needed to heat 1 kg of water at 0.4 MPa and 4 C to steam at 150 C and 0.4 MPa? D.) What is the enthalpy change needed to change 1 kg of water of a water-steam mixture of 60% quality to one of 80% quality if the mixture is at 150 C? E.) Calculate the change in H value for an isobaric change in steam from 0.8 MPa and 250 C to saturated liquid. F.) Repeat part E for an isothermal change to saturated liquid. G.) Does a state change from saturated vapor at 230 C to the state 100 C and 0.05 MPa represent an enthalpy increase or decrease? A volume increase or decrease? H.) In what state is water at 0.2 MPa and 120.21 C? At 0.5 MPA and 151.83 C? At 0.5 MPa and 153 C? I.) A 0.15 m^3 tank containing 1 kg of water at 1 MPa and 179.88 C has how many m^3 of liquid water in it? Could it contain 5 kg of water under these conditions? J.) What is the volume change when 2 kg of H2O at 6.8 MPa and 93 C expands to 1.6 bar and 250 C? K.) 10 kg of wet steam at 0.75 MPa has an enthalpy of 22,000 kJ. Find the quality of the wet steam.
