Question

Transcribed Image Text:Hot water (cph = 4188 J/kg*K) with mass flow
rate of 2.5 kg/s at 100 deg C enters a thin-
walled concentric tube counterflow heat
exchanger with a surface area of 23 m^2 and
an overall heat transfer coefficient of 1000
W/m2*K. Cold water (cpc = 4178 J/kg*K) with
mass flow rate of 5 kg/s enters the heat
exchanger at 20 deg C, determine (a) the heat
transfer rate for the heat exchanger and (b) the
outlet temperatures of the
cold and hot fluids.
