Question: Hot light oil is to be cooled by water from 250°F to 170°F in a doublepipe heat exchanger. The water is to be heated from 900F to 150°F. If the oil flow rate is 2.200 lbmassh and [C_p]_oil = 0.56 Btu/(lbmass °F), find the water flow rate. If U. = 45 Btu/(h ft2 °F), compare countercurrent and concurrent heat exchangers. Assuming a clean heat exchanger, which resistance - water side, metal, or oil side - would you expect to be the controlling resistance?
