2500kj of heat is absorbed to produce 1 kg of wet steam at a preasure of 1300 kPa from feed water 25(degrees celcius). Thereafter the mixture is heated further at constant preassure to a temperature of 291,69degrees celcius) For superheated steam cp = 2,35 kj/kg.k. Calculate for 1 kg of steam:

1.the initial dryness fraction.

2.the heat required to produce superheated steam from the feed water.

3. the increase in specific volume from the wet state to the superheated state.

4.The increase in internal energy from the wet state to the superheated state.
