• 98 Pa

• 1 Pa

Pressure intensity or force due to pressure gradient for fluid at rest is considered as which kind of force?

• Surface force

• Body force

• Force due to motion

• None of the mentioned

The pressure at any given point of a non-moving fluid is called the ____________

• Gauge Pressure

• Atmospheric Pressure

• Differential Pressure

• Hydrostatic Pressure

What type of liquids are measured using a manometer?

• Heavy liquids

• Medium Liquids

• Light Liquids

• Heavy and light liquids

If fluid is at rest in a container of a narrow mouth at a certain column height and same fluid is at rest at same column height in a container having broad mouth, will the pressure be different at certain depth from fluid surface.

• Pressure will be same for both.

• Pressure will be more for narrower mouth

• Pressure will be less for narrower mouth

• None of the mentioned

In the inverted U-tube Differential manometer, how is the specific gravity of manometric fluid used relative to the fluid flowing in the pipes

• Specific gravity is more than that of fluid flowing in pipes

• Specific gravity is less than that of fluid flowing in pipes

• Specific gravity is equal to that of fluid flowing in pipes

• None of the mentioned

Calculate the hydrostatic pressure for water moving with constant velocity at a depth of 5 m from the surface.

• 49 kN/m2

• 98 kN/m2

• since fluid is in motion, we cannot analyse

• None of the mentioned
