Heat Transfer - Engineering
Q1: In a multipass shell and tube heat exchanger, tube side return pressure loss is equal to __________ the velocity head.A twice
B four times
C square root of
D square of
ANS:B - four times n a multipass shell and tube heat exchanger, the tube side return pressure loss is equal to the square of the velocity head. The pressure loss (or drop) in a fluid flow system is often expressed in terms of the velocity head, which is defined as 2gv2, where v is the velocity of the fluid and g is the acceleration due to gravity. Therefore, the correct option is: square of |
