Task 2 Your second customer wants to choose a parallel-flow-plate-type heat exchanger that contains two fluids (oil and water) separated by a thin metal sheet as shown in figure 1 for cooling the lubricating oil. The heat exchanger is insulated by a 130-mm glass fiber insulation (paper faced, 28 kg/m³). The heat transfer coefficients of water and oil are 1200 and 900 W/m² °C, respectively. 2 m Ts cm S cm 5 cm OIL Water Figure 1: A parallel-flow-plate-type heat exchanger. STEP 1 The flow rate of cooling water is 0.2 kg/s, and the flow rate of oil the is 0.1 kg/s. Also, the oil and water enter at temperatures of 100 and 30°C, respectively, and the outlet temperature of the oil is 40°C. if the top surface of the heat exchanger is exposed to an atmospheric air (T=10°C) that is parallel to the flows and maintains a heat transfer coefficient of h = 70 W/m2 K, which includes the effects of radiation, help your customer to calculate the heat losses from it.
Need answer ASAP In a counter-current-flow tubular heat exchanger, a liquid food (milk),flowing in the inner pipe, is heated from 20 to 40°C. In theouter pipe the heating medium (water) cools from 90 to50°C. The overall heat-transfer coefficient based on the insidediameter is 2000 W/(m^2-°C). The inside diameter is 5 cm andlength of the heat exchanger is 10 m. The average specific heatof water is 4.181 kJ/(kg-°C). Calculate the mass flow rate ofwater in the outer pipe. Compare the amount of milk being heated to concurrent design.
