6.3. Example Problem 5: Venturimeter

Try these first

1. 1.

   What is the main purpose of a venturimeter?

   Hint

   Think about a device that measures speed or quantity.

2. 2.

   Define discharge coefficient in the context of a venturimeter.

   Hint

   It compares real measurements to ideal calculations.

3. 3.

   What is the main function of a venturimeter?

   • To pressurize gases
   • To measure fluid flow rate
   • To heat fluids

   Hint

   Think about how we measure how much liquid moves through a pipe.

4. 4.

   True or False: Bernoulli's equation can be applied to compressible fluids.

   • True
   • False

   Hint

   Consider the primary assumption of the equation.

5. 5.

   Given a venturimeter with diameter A1 = 15 cm and A2 = 7.5 cm, calculate the flow rates if pressure differences read 2.5 m of water.

   Hint

   Remember to apply the equations consistently and check unit conversions.

6. 6.

   A venturimeter indicates a discharge coefficient of C_d = 0.95 with a theoretical flow rate of 50 L/s. What is the actual flow rate?

   Hint

   Rearrange the equation appropriately to isolate Q_actual.
