The mass per unit volume of a fluid is called its

• coefficient.
• density.
• specific gravity.
• viscosity.

A column of water will exert a pressure of 0.098 bar for each meter of water. If a <br />a turbine is installed at the bottom of a dam which has 50 meters height of water, <br />calculate the pressure exerted on the turbine.

• 0.098 bar.
• 1.0 bar.
• 4.9 bar.
• 510.2 bar.

What’s the correct unit for Weight?

• Kg.
• m/s.
• N.
• N/m2.

Which of the following terms has the unit of N/m2?

• Density.
• Force.
• Pressure.
• Weight.

The unit for Force is

• Kg.
• m/s.
• N.
• N/m2.

The pressure exerted by a liquid at any given point or location in a vessel

• depends upon the height of liquid above it and the shape of the vessel.
• depends upon the height of liquid above it and is independent of the shape of the vessel.
• is independent of the height of liquid above it and the shape of the vessel.
• depends on the shape of the vessel and is independent to the height of liquid above it.

A vacuum means the pressure is

• equal to one atm.
• less than one atm.
• more than one atm.
• equal to two atms.

If the pressure at the bottom of the tank is 2.76 bar absolute and the atmospheric pressure is 1.01 bar. What is the gauge pressure at the bottom of the tank?

• 1.01 bar gauge.
• 1.75 bar gauge.
• 2.76 bar gauge.
• 3.77 bar gauge.

Water boils at 1000 C under normal atmospheric pressure. If the water is at pressure 0.6 bar lesser than the atmospheric pressure (example on a very tall mountain), its boiling point will be

• less than 1000 C.
• more than 1000 C.
• equal to 1000 C.
• equal to 1600 C.
