Ashell-and-tube heat exchanger with single shell and two passes tube (1-2) uses hot water on the tube side to heat oil on the shell side. there are 20 tube passes made of copper have inner and outer diameters of 20 and 24 mm and the length of the heat exchanger is 3 m. water enters each tube at a rate of 0.2 kg/s at 87 °c and leaves at (a) calculate the convective heat transfer coefficient of the tube inner side. (b) calculate the overall heat transfer coefficient based on the pipe outer area if the shell side convective coefficient is 875 w/(m^2k). (c) calculate the total heat exchange area available (d) calculate the total heat load of the heat exchanger (e) calculate lmtd if the value for f is 0.9
