A boiler takes in feed water at 70 °C and generates steam at a pressure of 10 bar and dryness fraction 0.92. The wet steam enters a superheater and emerges with the same pressure at a temperature of 400 °C. If the steam flow rate is 5 tonnes per hour, determine (i) the rate at which heat transfer takes place in the boiler and (ii) the rate at which heat transfer takes place in the superheater. State any assumptions you have made in relation to the steady flow equation for the process.

Question
A boiler takes in feed water at 70 °C and generates steam at a pressure of 10 bar and dryness
fraction 0.92. The wet steam enters a superheater and emerges with the same pressure at a
temperature of 400 °C. If the steam flow rate is 5 tonnes per hour, determine (i) the rate at
which heat transfer takes place in the boiler and (ii) the rate at which heat transfer takes place
in the superheater. State any assumptions you have made in relation to the steady flow
equation for the process.
