WebA liquid-to-liquid counterflow heat exchanger is used as part of an auxiliary system at a nuclear facility. The heat exchanger is used to heat a cold fluid from 120°F to 310°F. Assuming that the hot fluid enters at 500°F and leaves at 400°F, calculate the LMTD for the exchanger. Solution: ΔT 2 = 400°F − 120°F = 280°F ΔT 1 = 500°F − 310°F = 190°F WebIn an air-cooled heat exchanger, hot process fluid flows through a finned tube.
