The mass flow rate, specific heat, and inlet temperature of the tube-side stream in a double-pipe, parallel-flow
Question:
The mass flow rate, specific heat, and inlet temperature of the tube-side stream in a double-pipe, parallel-flow heat exchanger are 2700 kg/h, 2.0 kJ/kg·K, and 120°C, respectively. The mass flow rate, specific heat, and inlet temperature of the other stream are 1800 kg/h, 4.2 kJ/kg·K, and 20°C, respectively. The heat transfer area and overall heat transfer coefficient are 0.50 m2 and 2.0 kW/m2·K, respectively. Find the outlet temperatures of both streams in steady operation using
(a) The LMTD method
(b) The effectiveness–NTU method.
