7.1.1. Lecture - 04

Try these first

1. 1.

   What is Pascal's Law?

   Hint

   Think about hydraulic systems.

2. 2.

   Define gauge pressure.

   Hint

   It's how much pressure is above the surrounding atmosphere.

3. 3.

   What does Pascal's law state?

   • Pressure decreases with depth.
   • Pressure increases with temperature.
   • Pressure applied to a confined fluid is transmitted equally.
   • Pressure varies in different directions.

   Hint

   Think about how pressure acts in hydraulic systems.

4. 4.

   True or False: Gauge pressure is measured relative to atmospheric pressure.

   • True
   • False

   Hint

   Consider how pressure measurements are compared.

5. 5.

   If a dam is 50 meters high, calculate the hydrostatic pressure at the base, given the density of water is 1000 kg/m³.

   Hint

   Consider both the density of water and the height of the water column.

6. 6.

   A 1000 L tank holds oil with a specific gravity of 0.8. Calculate the pressure at the bottom of the tank.

   Hint

   First, find the height of the oil in the tank.
