QUESTION 6 En. Karim recently bought a 2-shell passes and 12-tube passes type heat exchanger for his metal factory to reduce the hot oil (cp = 2200 J/kg.K) temperature. The hot oil enters the heat exchanger through the shell passes at 160 °C with a flow rate of 0,2 kg/s. The coolant fluid used to reduce the hot oil temperature is water (cp = 4180 J/kg.K). Water flows through the heat exchanger pipe at 18 °C and at flow rate of 0.1 kg/s. The tube inside the heat exchanger is made of 1.8 cm diameter copper tube and the length is 3 m. If the overall heat transfer coefficient is 340 W/m².K, evaluate and discuss your finding for the following parameters; i. The maximum rate of heat transfer, ii. The actual rate of heat transfer, iii. The outlet temperatures of the water, and iv. The outlet temperatures of the oil.

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

Please help me .. answer my Question , I don't want to quote or plagiarize, don't use your handwriting just use MS Word . Question (b)
Task 03 B) Double-pipe heat exchangersare used in many industries because of their low design and maintenance costs, flexibility, and low installation cost. They are mainly used for sensible heating or cooling of process fluids in applications of small heat transfer Water at the rate of 68 kg/min is heated from 35 0C to 75 0C by an oil having specific heat of 1.9 kg/kJ.0C . The fluids are used in a counter flow double-pipe heat exchanger, and the oil enters in the exchanger at 175 0C and leaves at 140 0C . The overall heat transfer coefficient is 320 W/m2. 0C . Apply heat transfer formulae to heat exchangers and calculate the heat exchanger area.
Draw the Temperature & compute the LMTD for CO-CURRENT & COUNTER-CURRENT flow heat exchanger. A single-pass tubular type heat exchanger heats air from 35 C to 80 C. Exhaust gas from DIESEL engine at 350 C is used as heating medium. If the final temperature of exhaust gas leaving the heat exchanger is 140 C, what is the LMTD?
