A plate and frame heat exchanger with a 1-1/U configuration has water (fouling factor = 0.00005 h-ft2-°F/Btu) for both hot and cold fluids. The heat exchanger has 125 plates.
The horizontal port distance is 15 in and the vertical port distance is 27 in. The plates are 0.04 in thick and stamped with a 65° chevron pattern. The plate pitch is 0.15 in and the plate enlargement factor is 1.17. The port diameters are 1.5 in. The plates are made from AISI 316 stainless steel. Hot water enters the heat exchanger at 135°F with a flow rate of 72,000 lbm/h. The cold water, flowing at a rate of 68,000 lbm/h, enters the heat exchanger at 55°F. Determine the thermal and hydraulic performance of this heat exchanger. Report your answers in a table similar to Table 5.17.
