# Determine.. should supplied to 2 kg of water solved problem

#### Determine the amount of heat, which should be supplied to 2 kg of water at 25°C to convert it into steam at 5 bar and 0.9 dry.

Determine the amount of heat, which should be supplied to 2 kg of water at 25°C to convert it into steam at 5 bar and 0.9 dry.

1. A vessel having a volume of 0.6 m3 contains 3.0 kg of liquid water and water vapour mixture in equilibrium at a pressure of 0.5 MPa. Calculate :
(i) Mass and volume of liquid ;
(ii) Mass and volume of vapour.

2. A vessel having a capacity of 0.05 m3 contains a mixture of saturated water and saturated steam at a temperature of 245°C. The mass of the liquid present is 10 kg. Find the following :
(i) The pressure, (ii) The mass, (iii) The specific uolun1e, (iv) The specific enthalpy, (v) The specific entropy, and (vi) The specific internal energy.

3. Determine the amount of heat, which should be supplied to 2 kg of water at 25°C to convert it into steam at 5 bar and 0.9 dry.
