(LMTD method) A 2 shell, 4 tube pass heat exchanger is being
used to heat 40 kg/s of a process fluid in the tubes from an inlet
temperature of 15°C to a target temperature of 70°C using
condensing steam at 150°C. The overall heat transfer coefficient
for a clean heat exchanger was Uo=1500W/m2.°C, however, the design
engineer neglected to take into account fouling of the heat
exchanger. After 5 years of use, fouling has occurred with fouling
factors of 0.0005m2.°C/W...

(40 pts) Shell-and-Tube Heat Exchanger to make Jell-O Cups A counter-current shell-and-tube heat exchanger is used to heat Jell-O solution (water + gelatin) using saturated steam on the shell side. Jell-O solution must be heated to at least 80 oC, poured into individual plastic cups, and then cooled to make the solid Jell-O cups. The Jell-O solution is heated with steam that enters the shell at 2.0 bar (Tsteam = 120oC) and exits as a saturated liquid. At this temperature...

A shell and tube heat exchanger with one shell pass and one tube pass will be used to condense the steam to saturated liquid, which enters the shell side as a saturated vapor at 400 K. The tube side contains R-134a refrigerant with an inlet temperature of 300 K and a mean velocity of 0.4 m/s. The steam flow rate is 1.5 kg/s. The tubes are made from AISI 302 stainless steel and have a 1" nominal diameter (Di =...

A shell-and-tube heat exchanger similar to the one shown in the Figure below is used to recover energy from waste water at 40°C to heat fresh water entering at 18°C. The mass flow rate of the waste water is 4 kg/s which is the same as that of the fresh water. Using the data given, calculate: (i) the optimum rate of energy recovery; the required heat transfer area; (iii) the temperature of the fresh water at exit. Shell fluid inlet...

Oil of unknown properties is heated in a shell-and-tube heat exchanger with one shell pass and 20 tube passes. The oil flows through the shell, and hot water flows inside the single copper tube that has an inner diameter of 20 mm, a wall thickness of 2 mm, and a length of 3 m per pass. The water enters at 360 K at a mass flow rate of 0.2 kg/s and leaves at 300 K. The inlet and outlet temperatures...
