3. In a food processing plant, Fluid A (cp = 4.31

3. In a food processing plant, Fluid A (cp = 4.31 kJ/kg.K) at 150 C and 3.5 kg/s entering the tube side is used to heat Fluid B (p = 2.05 kJ/kg-K) at x kg/s from a C to b C in a heat exchanger with an overall heat transfer coefficient of 120 W/m2.C. Based on the information given in TABLE Q3, by using effectiveness-NTU method, determine whether the heat exchanger is able to meet the heating process. State TWO (2) assumptions used in your calculation with justification. Suggest TWO (2) methods to increase the performance of the heat exchanger with justification. X: 8.5 a: 20 b:55 Surface Area, A : 40 Type of heat exchanger: Counter flow
