Q1:

In case of laminar flow through a circular pipe,

A momentum correction factor is 1.33

B energy correction factor is 2.00

C both (a) and (b)

D Neither (a) nor (b).

ANS:C - both (a) and (b)

the correct option is: Neither (a) nor (b). In laminar flow through a circular pipe, neither a momentum correction factor of 1.33 nor an energy correction factor of 2.00 are typically used. These correction factors are more commonly associated with turbulent flow conditions. For laminar flow in a circular pipe, the flow is smooth and well-ordered, and there is no need for such correction factors to adjust the calculations. The Hagen-Poiseuille equation describes laminar flow in a circular pipe without the need for additional correction factors.
