You are then asked by your supervisor to design a concentric tube heat exchanger to operate under the following conditions: Cold Fluid: m˙ = 0.125 kg/s Cp = 4200 J/kg K Ti = 40\deg C To = 95\deg C Hot Fluid: m˙ = 0.125 kg/s Cp = 2100 J/kg K Ti = 210\deg C If the heat exchanger is characterised by uniform overall heat transfer coefficient, using the LMTD method, determine: a) The maximum possible heat transfer rate. b) The heat exchanger effectiveness
