PLZ I want full answer with all solution steps A heat exchanger is to be designed to heat 32/68 mixture of ethylene glycol and water from 24 °C to 55 °C by a hot water stream from 79 °C to 42 °C. Flow rate of cold stream is 20 kg/s. Inlet pressure for both stream is 50 psi and the maximum pressure drop of 10 psi for cold stream and 8 psi for hot water are permissible. Report valid assumptions made for the design and give required justification. Estimate i) Heat Transfer, Corrected LMTD, ii) Tube bundle diameter (Using TEMA standards and Codes) and Tube cross sectional area iii) Heat transfer coefficient iv) Overall heat transfer coefficient v) Pressure Drop (Shell side & Tube Side) note: Assume any values for the missing data

Find the heat capacity of the hot and cold fluid.
I need answer in 1hr do it fast. A shell-and-tube heat exchanger is set at the one shell pass and two tube passes. Hot air enters the shell at 90°C, and leaves at 50°C, whose mass flow rate is 5 kg/s. Cold water enters the tube at 23°C, whose flow rate is 3 kg/s. What is the water outlet temperature? What is the overall UA of the heat exchanger? a) Draw the problem diagram. b) List all required properties and equations to solve this problem. c) Solve the problem
A dairy farm needs to chill the milk from 39°C (extraction temperature is the same as the cow's body temperature) to at least 12°C for storage by using an existing 4-m long concentric-tube heat exchanger. The inner tube of the heat exchanger is 4 cm in diameter. The milk (density: 1035 kg/m³, specific heat: 3860 J/kg.K) flows into the heat exchanger at a rate of 270 liters per hour. On the cold side, there is a supply of water at 2°C at a rate of 0.23 kg/s. The estimated overall heat transfer coefficient of the heat exchanger is 1084.2 W/m².K. It was measured that the water comes out of the heat exchanger at 11°C. Is the milk indeed being cooled down to at least 12°C by heat exchanger as required by the farm? Looking at the temperatures obtained from your calculation, put an argument whether the heat exchanger is a parallel-flow or a counter-flow heat exchanger. Approximate specific heat of water is 4200 J/kg.K. Neglect radiation.
