A one-shell and two-tube type heat exchanger has an overall heat transfer coefficient of 300 Btu/hft 2

Question:

A one-shell and two-tube type heat exchanger has an overall heat transfer coefficient of 300 Btu/h·ft2·°F. The shell side fluid has a heat capacity rate of 20,000 Btu/h·°F, while the tube side fluid has a heat capacity rate of 40,000 Btu/h·°F. The inlet temperatures on the shell side and tube side are 200°F and 90°F, respectively. If the total heat transfer area is 100 ft2, determine

(a) The heat transfer effectiveness

(b) The actual heat transfer rate in the heat exchanger.
