I have the following problem, and my solution is shown in the image, is it correct? Please verify the calculations You have been asked to design a heat exchanger to pasturize milk by raising it from 4°C to 72°C. The milk will be run through the heat exchanger at a flow rate of 15 liters/second. To create the heat exchanger, milk will flow through tubes with a 1.2 cm diameter. The tubes will be kept at a constant surface temperature through exposure to condensing steam at 100°C. You have been asked to calculate the following: • A single tube design – You must specify:∗ The length of the tube ∗ Average milk velocity∗ The pressure drop required to operate the exchanger∗ Give at least two reasons why a single tube heat exchanger is not feasible

In a facility, a counter-flow double-pipe heat exchanger is used to cool the fluid at a flow of 10.0 kg / s (Cp = 3.15 kJ / kgK) with an inlet temperature of 90 0C, and the surface area of the heat exchanger is As = 9 m2. The refrigerant (Cp = 4.2 kJ / kgK) enters the heat exchanger at a temperature of 10 ° C and a flow rate of 8.0 kg / h. Total heat transfer coefficient according to system data; ? = equation is given image. a) Calculate the heat transfer and heat exchanger exit temperatures.b) Existing heat exchanger is wanted to be changed. A seller offers an attractive discount to the plant authorities for two heat exchangers of the same property with a surface area of As = 5 m2. Since the pipe diameters in existing and new heat exchangers are the same, it is expected that the total heat transfer coefficient equation given above will also be valid for new heat exchangers. The vendor suggests that both heat exchangers can be operated in parallel in a counter-flow fashion, so that…

Steam at 1.6 MPa and 250°C is being throttled by an adiabatic steam valve to reduce its pressure to 0.5 MPa before it is being delivered to a heat exchanger (shown in Figure 1). At valve outlet, the steam at18,000 kg/hour flow into an adiabatic heat exchanger as hot fluid. Cooling water from water tap is used to cool the steam by circulating the water through the tubes inside the heat exchanger. At heat exchanger outlet, the cooling water temperature increased by 20°C as it passing through the heat exchanger, and steam leaves the heat exchanger as saturated vapor at 200 kPa. Determine: (a) the temperature of the steam at heat exchanger inlet; and (b) the mass flow rate of the cooling water required.
