Water is to be heated from 55° to 105°P at the rate of 275,000 gallhr in a single-pass shell-andtube heat exchanger consisting of l-in. schedule 40 steel pipe. The surface coefficient on the steam side is estimated to be 9,000 Btulhr-ft2 _ 0F. A pump is available that can deliver the desired quantity of water, provided that the pressure drop through the pipes does not exceed”
1 psi. Water is supplied at 100psia. The pump is to be used to make up the pressure drop. Saturated steam is supplied at 30 psia to the shell.
(a) Calculate the number of tubes in parallel and the length of each tube required to fulfill the requirement.
(b) Present the information on the TEMA form.
(c) How much steam is condensed on the shell side?
