1) A shell & tube heat exchanger has 2 passes in the tube side. The cold stream is water with 5°C inlet temperature and hot stream is water with 80°C inlet temperature. Both outlet temperatures are 60°C. Heat load is 60 KW and overall heat transfer coefficient is U=1100 W/m2°C. Determine heat transfer surface and mass flow rate of both streams. (score 5) 2) In the previous problem, if mass flow rate of hot stream become half, and input temperatures and U are constant, determine output temperatures and new heat load of the heat exchanger.(score 5)
