A shell-and-tube Heat exchanger with one shell exceed and two tube passes si to be designed to condense 3900 kg/hr of steam at 1 atm. Steam may be suppose to enter the shell side as a saturated vapor and leave as a saturated liquid. Water is used as cooling fluid in tubes with an inlet temperature of 40 oC. Consider over heat transfer coefficient values from Table:10.1, Verify a suitable design which specifies
(a)Number of tubes in every pass,
(b) outlet water temperature,
(c) tube diameter and length in every tube pass, and
(d) mass flow rate of water and final inside diameter of the shell that may needed.
It is desired to concentrate a NaOH solution from 12.5 % to 40% in a double effect evaporator. 50,000 lb/hr of feed solution enters the evaporator at 120 o F, and steam at 15 psig
