The pressure co-efficient is the ratio of pressure forces to __________ forces.
A. Viscous
B. Inertial
C. Gravity
D. Surface tension
Answer: Option B
Solution(By Examveda Team)
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.This Question Belongs to Chemical Engineering >> Fluid Mechanics
