Can someone help me with calculating the change in temperature of a stream through a heat exchanger?
I have the following info:
The Cold stream is Tin = 90,, Tout =100, the heat exchanger is 30 kW, and the hot stream is saturated steam, with deltaHvap = 1676 kj/kg and T in = 258 C

U of the heat exchanger is 1 kW/m^2*C but I don't think that's useful here?

Thank you so much!
