Q: In an industrial facility, a counterflow double-pipe heat exchanger
In an industrial facility, a counterflow double-pipe heat exchanger uses superheated steam at a temperature of 250°C to heat feedwater at 30°C. The superheated steam experiences...
See AnswerQ: A test is conducted to determine the overall heat transfer coefficient in
A test is conducted to determine the overall heat transfer coefficient in a shell-and-tube oil-to water heat exchanger that has 24 tubes of internal diameter 1.2 cm and length 2 m in a single shell. C...
See AnswerQ: A shell-and-tube heat exchanger is used for heating
A shell-and-tube heat exchanger is used for heating 14 kg/s of oil (cp = 2.0 kJ/kg⋅K) from 20°C to 46°C. The heat exchanger has one shell pass and six tube passes. Water enters the shell side at 80°C...
See AnswerQ: A one-shell-pass and eight-tube-passes
A one-shell-pass and eight-tube-passes heat exchanger is used to heat glycerin (cp = 0.60 Btu/lbm⋅°F) from 80°F to 140°F by hot water (cp = 1.0 Btu/lbm⋅°F) that enters the thin-walled 0.5-in-diameter...
See AnswerQ: What are the heat transfer mechanisms involved during heat transfer in a
What are the heat transfer mechanisms involved during heat transfer in a liquid-to-liquid heat exchanger from the hot to the cold fluid?
See AnswerQ: A shell-and-tube heat exchanger with two shell passes
A shell-and-tube heat exchanger with two shell passes and 12 tube passes is used to heat water (cp = 4180 J/kg⋅K) with ethylene glycol (cp = 2680 J/kg⋅K). Water enters the tubes at 22°C at a rate of 0...
See AnswerQ: Reconsider Prob. 22–60. Using appropriate software, investigate
Reconsider Prob. 22–60. Using appropriate software, investigate the effect of the mass flow rate of water on the rate of heat transfer and the tube-side surface area. Let the mass flow rate vary from...
See AnswerQ: A shell-and-tube heat exchanger with two shell passes
A shell-and-tube heat exchanger with two shell passes and 12 tube passes is used to heat water (cp = 4180 J/kg⋅K) in the tubes from 20°C to 70°C at a rate of 4.5 kg/s. Heat is supplied by hot oil (cp...
See AnswerQ: Repeat Prob. 22–62 for a mass flow rate of
Repeat Prob. 22–62 for a mass flow rate of 3 kg/s for water. Data from Prob. 22-62: A shell-and-tube heat exchanger with two shell passes and 12 tube passes is used to heat water (cp = 4180 J/kg⋅K) i...
