2.4. Equating Pressures between Points

Try these first

1. 1.

   Define hydrostatic pressure.

   Hint

   Think about what 'static' means in this context.

2. 2.

   What does a differential manometer measure?

   Hint

   Focus on the word 'differential.'

3. 3.

   What is the primary function of a differential manometer?

   • Measure temperature
   • Measure pressure difference
   • Measure flow rate

   Hint

   Consider its name and what it implies.

4. 4.

   True or False: Hydrostatic pressure increases with depth.

   • True
   • False

   Hint

   Think about gravity's role in fluid pressure.

5. 5.

   A cylindrical tank with a height of 10m is filled with 7m of water and 2.5m of oil (specific gravity 0.9). Calculate the pressure at the bottom of the tank.

   Hint

   Calculate contributions from both fluids separately for accuracy.

6. 6.

   In a pressurized gas system, a manometer shows 1.5 meters of mercury above atmospheric pressure and 0.4 m of water below it. Find the pressure in atmosphere.

   Hint

   Bear in mind to convert mercury pressure into appropriate units.
