For a 1 shell, 30 tube heat exchanger, the inlet temperature of the shell is 8 C and the outlet temperature of the shell is 32. The inlet temperature of the tube is 140 and the outlet temperature of the tube is 30. If the tubes have an outside diameter of 5 cm, how much heat is exchanged over a minute? You can assume the overall heat transfer coefficient is 240 W/m2K. a. Calculate the LMTD for this heat exchanger. LMTD= (Tz-t) - CT -+2) (Tルーt) (T-t2)

3) For a 1 shell, 30 tube heat exchanger, the inlet temperature of the shell is 8 C and the outlet
temperature of the shell is 32. The inlet temperature of the tube is 140 and the outlet
temperature of the tube is 30. If the tubes have an outside diameter of 5 cm, how much heat is
exchanged over a minute? You can assume the overall heat transfer coefficient is 240 W/m?K.
a. Calculate the LMTD for this heat exchanger.
LMTD= (Tz- ti) - CTI -+2)
(T.-t2)
