1.1. Lecture- 04

Try these first

1. 1.

   What is a differential manometer?

   Hint

   Think about devices used in fluid measurement.

2. 2.

   How do you calculate pressure at a certain height in a fluid?

   Hint

   Recall the relationship between pressure, density, and height.

3. 3.

   What is the purpose of a differential manometer?

   • To measure flow rate
   • To measure temperature
   • To measure pressure differences
   • None of the above

   Hint

   Think about what measurements relate to pressures.

4. 4.

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

   • True
   • False

   Hint

   Think about the definition of specific gravity.

5. 5.

   An oil tank is 10m tall and filled with 6m of vegetable oil (specific gravity 0.95) and 4m of water. Calculate the pressure at the bottom of the tank.

   Hint

   Calculate pressure contributions separately.

6. 6.

   Explain why the specific gravity of a fluid is significant in hydraulic engineering applications.

   Hint

   Consider the impact of density on buoyancy and pressure calculations.
