3. (25 pt) A double-pipe, parallel-flow heat exchanger uses oil (Cp=1.88kJ/kg.C) at an inlet temperature of 205C to heat water (Cp=4.18kJ/kgC) flowing at 225kg/h, from
3. (25 pt) A double-pipe, parallel-flow heat exchanger uses oil (Cp=1.88kJ/kg.C) at an inlet temperature of 205C to heat water (Cp=4.18kJ/kgC) flowing at 225kg/h, from 16C to 44C. The oil flow rate is 270kg/h. Determine: a) the maximum possible heat transfer rate, b) the required heat exchanger area for an overall heat transfer coefficient of 340W/m2C, c) the number of transfer units (NTU), d) the effectiveness of the heat exchanger
