24.3.2. Venturimeter Functionality

Try these first

1. 1.

   What is the function of a venturimeter?

   Hint

   Think about how pressure changes in a fluid flow.

2. 2.

   What does Bernoulli's equation relate?

   Hint

   Consider what happens to energy in fluid mechanics.

3. 3.

   What creates the pressure difference in a venturimeter?

   • Converging flow area
   • Fluid temperature
   • Pipe material

   Hint

   Look at how the design of the venturimeter influences flow.

4. 4.

   True or False: The coefficient of discharge is always equal to 1.

   • True
   • False

   Hint

   Consider why real-world scenarios differ from ideal calculations.

5. 5.

   Given a venturimeter with inlet diameter 0.2m and outlet diameter 0.1m, and a pressure difference of 500 Pa, calculate the flow rate if the coefficient of discharge is 0.95.

   Hint

   Compute area using the diameters and consider the effects of the pressure difference.

6. 6.

   Discuss how the design of a venturimeter influences the kinetic energy correction factor for turbulent flow.

   Hint

   Investigate how turbulence alters flow patterns versus laminar flows.
