[#491] Normal depth in open channel flow is the depth of flow in the channel
Correct Answer

(A) Corresponding to uniform flow

[#492] Which of the following is not concerned with the fluid-particle interaction?
Correct Answer

(D) Weber number

[#493] Which of the following is dimensionless?
Correct Answer

(B) Fanning friction factor

[#494] The pressure co-efficient is the ratio of pressure forces to __________ forces.
Correct Answer

(B) Inertial

Explanation

Solution: The pressure coefficient is the ratio of pressure forces to inertial forces. In fluid mechanics, the pressure coefficient is a dimensionless quantity that relates the pressure at a certain point to the free stream dynamic pressure. Inertial forces are associated with the motion and acceleration of fluid particles. Therefore, in this context, the correct option is Option B: Inertial .

[#495] Pressure co-efficient is the ratio of pressure forces to __________ forces.
Correct Answer

(B) Inertial
