Question

Pressure force is equal to the

• A. Product of pressure intensity and cross-sectional area of the flowing fluid.
• B. Product of shear stress and area of the flow.
• C. Product of surface tension and length of surface of the flowing fluid.
• D. Product of mass and acceleration due to gravity.

Answer 1

Answer:

B. Product of shear stress and area of the flow.

Pressure force is the force per unit area and is calculated by dividing force by area. Pressure force is equal to the product of pressure intensity and cross-sectional area of the flowing fluid.
