24.3. Experimental Setups in Fluid Measurement

Try these first

1. 1.

   What does an orifice meter measure?

   Hint

   Think about how flow is quantified in different applications.

2. 2.

   Define dynamic pressure.

   Hint

   Consider what happens to a fluid in motion.

3. 3.

   What does an orifice meter measure?

   • Flow rate
   • Energy loss
   • Static pressure

   Hint

   Think about what an orifice's function is.

4. 4.

   True or False: The coefficient of discharge (C) is the ratio of theoretical discharge to actual discharge.

   • True
   • False

   Hint

   Recall the definition of the coefficient of discharge.

5. 5.

   Given an orifice meter with a diameter of 5 cm, if the pressure drop across it is 2000 Pa, and fluid density is 1000 kg/m³, calculate the flow rate.

   Hint

   Apply the formula for discharge through an orifice.

6. 6.

   A pipe has a diameter of 10 cm and experiences high turbulent flow with an average velocity of 3 m/s. Calculate the appropriate kinetic energy correction factor.

   Hint

   Consider the average versus actual flow scenario for correction.
