Water is used to cool ethylene glycol in a 60-ft-long double pipe heat exchanger made of 4-std and 2-std (both type M) copper tubing. The water inlet temperature is 60°F and the ethylene glycol inlet temperature is 180°F. The flow rate of the ethylene glycol is 20 lbm/s, while that for the water is 30 lbm/s. Calculate the expected outlet temperature of the ethylene glycol and determine the pressure drop expected for both streams. Assume counterflow, and place the ethylene glycol in the inner tube.

The clean U for an exchanger is 770 BTU/(hr 0 F ft2). Its tube area is 550 ft2. After operating for several months, it is heating water from 40 0F to 150 0F at a flow rate of 200 GPM with a heating fluid on the shell entering at 300 0F and exiting at 170 0 F. Has the overall U decreased significantly? how many 1.0 inch diameter, 20 ft long tubes would it take to equal the 550 ft2 area?
1) For a concentric counter-flow heat exchanger, hot oil is coming in the tube of the shell/tube heat exchanger and it's cooled by water that surrounds it in the shell. Calculate what is the required length of the heat exchanger tube in order to perform the necessary cooling. Assume there is negligible heat loss to the surroundings and negligible conductive heat resistance between the two fluids. Mass flow rate of oil = 0.17 kg/s Oil heat capacity = 2375 J/kg-ºC Oil convective heat transfer coefficient = 39.7 W/m²-°C Oil enters tube at temperature = 130 °C Oil leaves tube at temperature = 83 °C Water convective heat transfer coefficient = 2190 W/m²-°C Water enters shell at temperature 15 °C Water leaves shell at temperature = 74 °C Inner diameter = 4.5 cm Outer diameter = 6.5 cm

Xylene out of the storage tank at a temperature of 308 K will be heated to a temperature of 343 K. For this purpose, 4500 kg/hour n-Butanol is used which will experience a decrease in temperature from 358 K to 338 K. To exchange heat between the two fluids, it was decided to use 5 (five) double pipe heat exchangers arranged in series each with a length of 6 m. The pipe diameters in the heat exchangers are 78 mm and 53 mm. Can you determine the fouling factor of the heat exchanger and the pressure drop that occurs in the heat exchanger

The refrigerant condensing temperature is 35°C, the heat rejection ratio of the plant is 1.35. The condenser has 24 steel tubes of 21 mm OD and 13.65 mm ID. Determine the length of the tubes.
Water must be heated from 15 to 50°C in a simple double-pipe heat exchanger at a rate of 3,500 kg/h. The water is flowing inside the inner tube with steam condensing at 110°C on the outside. The tube wall is so thin that the wall resistance may be neglected. Assume that the steam-film coefficient h_0 is 11 kW/m^2 °C. What is the length of the shortest heat exchanger that will heat the water to the desired temperature, considering an optimal diameter for the tube?

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.
