A simple heat exchanger is made by welding one-half of a 1¾-in drawn steel tube to a flat plate as shown in Fig. 9.30. Water at 40°F flows in the enclosed space and cools the plate. Compute the volume flow rate required so that the Reynolds number of the flow is 3.5 × 104. Then, compute the energy loss over a length of 92 in.
