Pressure co-efficient is the ratio of pressure forces to __________________________ forces?
Correct answer: B. Inertial
- A. Gravity
- B. Inertial
- C. Viscous
- D. None of these
Explanation
The pressure coefficient compares pressure forces with inertial forces, typically written as pressure difference divided by one-half density times velocity squared. Gravity and viscous forces belong to other dimensionless force ratios.
