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. Figure 1: A parallel-flow-plate-type heat exchanger. Your task to help your costumer by doing the following steps: 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.

Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
Question
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.

Your task to help your costumer by doing the following steps:
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.
STEP 2
Calculate the total heat transfer rate through this heat exchanger. Assume the thickness
of the thin metal sheet.
