A heat exchanger produces dry steam at 100°C from feed water at 15°C at a rate of 2.4 kgs?1. The heat exchanger receives heat energy at a rate of 6.5 MW from the fuel used. The specific heat capacity of water is 4187 Jkg?1K?1 and its specific latent heat of vaporisation is 2257 KJkg?1.i)Determine the heat energy received per kilogram of steam produced.
I answered this question 2 weeks ago, and the solution method hasn't changed. 6.5 MW/(2.4 kg s^(-1)) = 2708 kJ/kg The other quantities given must be relevant to parts (ii) and (iii) of the problem (or however many other parts there are).
