1.What will happen when the pressure of feed water is increased?
Boiling point of water decreases and enthalpy of evaporation increases Boiling point of water increases and enthalpy of evaporation decreases Boiling point of water increases and enthalpy of evaporation increases None of these
2.For which of the following instances the throttling calorimeter can be used alone.
Very low dryness fraction upto 0.7 Dryness fraction of only low pressure steam High dryness fraction upto 0.98 Throttling calorimeter cannot be used alone
3.In throttling process
Reversible and adiabatic Frictionless Reversible and isothermal. Irreversible and adiabatic
4.Among the following which is not property of the system?
Pressure Temperature Heat Specific volume
5.In isothermal process
Change in internal energy is zero Pressure remains constant Volume remains constant Enthalpy change is maximum
