Answer to Question #60561 in Mechanical Engineering for Bryan Tezna

Question

Task 2
A heat exchanger produces dry steam at 100 C from feed water at 30C 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^-1K^-1 and its specific latent heat of vaporisation is 2257 Jkg^-1.
A) determine the heat energy received per kilogram of steam produced.
B)determine the output power of the heat exchanger and its thermal efficiency.
