Heat Exchanger Problem
1
10-59 A counterflow double-pipe heat exchanger is employed to heat 30 kg/s of water from 20 to 40 °C with a hot oil at 200 °C. The overall heat-transfer coefficient is 275 W/m 2 · °C. Determine effectiveness and NTU for exit oil temperatures ranging from 190 until 80 °C. Plot and discuss your results.
