Question: Task 2 part A The second task concerns a heat exchanger that takes in feed water at 30'c and produces dry steam at 100 C.

Task 2 part A The second task concerns a heat exchanger that takes in feed water at 30'c and produces dry steam at 100 C. You will need to calculate the heat energy received per kilogram of steam produced and the thermal efficiency of the heat exchanger. A heat exchanger produces dry steam at 100 C from feed water at 30'C at a rate of 1.5 kgs-1. The heat exchanger receives heat energy at a rate of 600 kW from the fuel used. The specific heat capacity of water is 4187 Jkg" K- and its specific latent heat of vaporisation is 2257 Jkg-1. i) Determine the heat energy received per kilogram of steam produced. ii ) Determine the output power of the heat exchanger iii) And its thermal efficiency
