1.2. Basics of Fluid Mechanics- 1 (Contnd.)

Try these first

1. 1.

   What device do we use to measure pressure in fluids?

   Hint

   It's a common term in fluid mechanics.

2. 2.

   What is the formula for hydrostatic pressure?

   Hint

   Think about the factors that contribute to pressure due to fluids.

3. 3.

   What does a manometer measure?

   • Temperature
   • Fluid Volume
   • Pressure Difference

   Hint

   Consider what fluid property relates closely to pressure.

4. 4.

   True or False: Specific gravity is the ratio of the density of a substance to the density of air.

   • True
   • False

   Hint

   Think about the reference substance used in calculations.

5. 5.

   A tank contains 5 meters of water and 3 meters of oil with a specific gravity of 0.95. Calculate the pressure at the bottom.

   Hint

   Don't forget the standard unit weight of water.

6. 6.

   Two points in an oil-filled manometer show a height difference of 0.05 m due to a temperature change. Calculate the resulting pressure change.

   Hint

   Remember the unit weight of oil needs to include its specific gravity.
