The purchased cost of a shell-and-tube heat exchanger (floating-head and carbon-steel tubes) with 100 m2 of heating surface was $4500 in 1990. What will be the 1990 purchased cost of a similar heat exchanger with 20 m2 of heating surface if the purchased cost capacity expo- nent is 0.60 for surface areas ranging from 10 to 40 m2? If the purchased cost capacity expo- nent for this type of exchanger is 0.81 for surface areas ranging from 40 to 200 m2, what will be the purchased cost of a heat exchanger with 100 m2 of heating surface in 2000?

A shell-and-tube heat exchanger uses cooling water in the tubes. There are two pressure gages installed on the the water side to the heat exchanger. Gage 1 (P1) is installed on the inlet water line, which is connected to the lower nozzle, while Gage (P2) is installed on the discharge water line, which is connected to the upper nozzle. Both pressure gages are very near the nozzle flanges. The pressure drop from each pressure gage to the exchanger channel is...

A two-pass shell and tube heat exchanger has an overall conductance of 450 W/m2 oC when used as a condenser for a large air conditioning system. Refrigerant R-134a enters thecondenser at 20 kg/ s as a saturated vapor at 70oC and leaves as a saturated liquid. If cooling water enters at a rate of 60 L/s, 10oC, determine the outlet temperature of the cooling water and the effective area of the condenser.

The condenser of a thermoelectric plant is a shell and tube heat exchanger consisting of a shell and 30,000 tubes, each of which executes two steps. The tubes are thin- walled with D = 25 mm, and the steam condenses on its outer surface with a convection coefficient of ho = 11 kW/m2 K. The heat transfer that the exchanger must perform is 2,000 MW, and this is carried out by passing cooling water through the pipes at the rate...
