Question

A fixed-tubesheet heat exchanger will use 3/4 in. tubes, 20-ft long on 1 in. triangular pitch. It will require two shell-side passes and a total of four tube-side passes. A minimum of 1100 tubes will be required to handle the heat duty. If standard type E shells are used: (a) What size shells will be required? (b) What will be the approximate tube count for the exchanger?

Answer 1

Answer:

Most shell-and-tube heat exchangers are either 1, 2, or 4 pass designs on the tube side. This refers to the number of times the fluid in the tubes passes through the fluid in the shell. In a single pass heat exchanger, the fluid goes in one end of each tube and out the other.
