this heat exchanger is designed so that
00:00:02.030 00:00:02.040 the tube side fluid passes the shell
00:00:04.130 00:00:04.140 side fluid twice the tube side fluid
00:00:07.610 00:00:07.620 enters here and is directed through half
00:00:10.250 00:00:10.260 of the tubes by the inlet head after
00:00:12.709 00:00:12.719 passing through the first half of the
00:00:14.539 00:00:14.549 tubes the fluid is directed into the
00:00:16.790 00:00:16.800 rest of the tubes by the return head the
00:00:19.490 00:00:19.500 fluid then passes through the rest of
00:00:21.349 00:00:21.359 the tubes and is directed out of the
00:00:23.359 00:00:23.369 heat exchanger besides the number of
00:00:27.140 00:00:27.150 passes the flow paths inside a heat
00:00:29.630 00:00:29.640 exchanger can also be used to categorize
00:00:32.089 00:00:32.099 types of heat exchangers there are three
00:00:35.120 00:00:35.130 general categories for the flow path
00:00:37.100 00:00:37.110 through a heat exchanger parallel flow
00:00:40.330 00:00:40.340 cross flow and counter flow in a
00:00:46.160 00:00:46.170 parallel flow heat exchanger the shell
00:00:48.680 00:00:48.690 side fluid and the tube side fluid move
00:00:51.110 00:00:51.120 in the same direction in this heat
00:00:53.540 00:00:53.550 exchanger the tube side fluid passes
00:00:56.029 00:00:56.039 through the tubes in this direction and
00:00:58.069 00:00:58.079 the shell side fluid passes around the
00:01:01.130 00:01:01.140 tubes in the same direction
