Heat Transfer - Engineering

Q1:

In a shell and tube heat exchanger, square pitch compared to triangular pitch

A gives a higher shell side pressure drop.

B gives a lower shell side pressure drop.

C can pack more surface area into a shell of given diameter.

D none of these.

ANS:B - gives a lower shell side pressure drop.

n a shell and tube heat exchanger, compared to a triangular pitch, a square pitch:

  • Gives a lower shell side pressure drop.
A square pitch arrangement allows for more direct flow paths for the fluid through the shell side, resulting in lower pressure drop compared to a triangular pitch arrangement. So, the correct option is: gives a lower shell side pressure drop.
