24.5.1. Static Pressure

Try these first

1. 1.

   Define static pressure.

   Hint

   Think about fluids that aren't moving.

2. 2.

   What is dynamic pressure?

   Hint

   Relate this to fluid velocity.

3. 3.

   What is static pressure?

   • Pressure at rest
   • Pressure in motion
   • Stagnation pressure

   Hint

   Think about pressure when fluid isn't moving.

4. 4.

   True or False: Stagnation pressure is the sum of static and dynamic pressures.

   • True
   • False

   Hint

   Recall the definition of stagnation pressure.

5. 5.

   A tank has water with a height of 10m. Calculate the static pressure at the bottom of the tank (use density of water = 1000 kg/m³, g = 9.81 m/s²).

   Hint

   Use the formula for static pressure involving height.

6. 6.

   In a pipe with a flow velocity of 5 m/s and water density of 1000 kg/m³, calculate the dynamic pressure and stagnation pressure if the static pressure is 150,000 Pa.

   Hint

   Calculate dynamic pressure first, then add to the static pressure.
