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 90^oF to 150°F.

If the oil flow rate is 2.200 lbmass/h and [C_P],_oil, = 0.56 Btu/(lbmass
^oF), find the water flow rate.

If U_O
= 45 Btu/(h ft²
^oF), 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?
