C- Hot engine oil is to be cooled in a double-tube counter-flow heat exchanger. The copper inner tubes have a diameter of 2.5 cm and negligible thickness. The inner diameter of the outer tube (the shell) is 4 cm. Water flows through the tube at a rate of 0.42 kg/s, and the oil through the shell at a rate of 0.91 kg/a. Taking the average temperatures of the water and the oil to be 52 C and 95°C, respectively, determine the overall heat transfer coefficient of this heat exchanger. Nu or Turbulent flow

In a thin-walled double-pipe heat exchanger, when is the approximation U = hi a reasonable one? Here U is the overall heat transfer coefficient and hi is the convection heat transfer coefficient inside the tube.
Water is stored in a large, well-insulated storage tank at 21.0°C open to atmosphere. It is pumped at a rate of 40 m3/h to another tank 25 m above, which is also open to atmosphere. The motor driving the pump supplies energy at the rate of 9.5 kW. The water passes through a heat exchanger where 255 kW of heat is added to the water. The total friction loss (ΣF) in the system is 90.25 J/kg. Determine the final temperature of the water at the second tank.

Consider two double-pipe counter-flow heat exchangers that are identical except that one is twice as long as the other one. Which heat exchanger is more likely to have a higher effectiveness?
A shell-and-tube heat exchanger with 1-shell pass and 20–tube passes is used to heat glycerin in the shell, with hot water in the tubes. The tubes are thin-walled and have a diameter of 4 cm and length of 2 m per pass. The water enters the tubes at 1000C at a rate of 0.5 kg/s and leaves at 550C. The glycerin enters the shell at 150C and leaves at 550C. Determine the mass flow rate of the glycerin and the overall heat transfer coefficient of the heat exchanger.
Concentric Tube Heat Exchanger What are thermal and hydrodynamic entrance length? Are either (or both) of them an issue for the experiment? Why or why not?
Consider a shell-and-tube water-to-water heat exchanger with identical mass flow rates for both the hot- and cold-water streams. Now the mass flow rate of the cold water is reduced by half. Will the effectiveness of this heat exchanger increase, decrease, or remain the same as a result of this modification? Explain. Assume the overall heat transfer coefficient and the inlet temperatures remain the same.
