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

your answer would be a. 12.5 kg

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
