May 27, 2016 · Step 6:For heat transfer coefficient calculation. Hot water at 75 °C is allowed to pass through the inner pipe of heat exchanger at 1000 LPH (m h = 0.2715 kg/s). Cold water is now allowed to pass through the outer pipe of heat exchanger in counter current direction at 1000 LPH (m c = 0.2715 kg/s). The inlet and outlet temperatures for both hot water and cold water (T1T4) are recorded only
Pipe Heat Exchanger - an overview ScienceDirect TopicsA double-pipe heat exchanger will be used to cool a hot stream from 350°F to 250°F by heating a cold stream from 80°F to 120°F. The hot stream will flow in the inner pipe, which is 2-in. schedule 40 carbon steel with a thermal conductivity of 26 Btu/h · ft2 · °F.
