25.2. Pump and Turbine Systems

Try these first

1. 1.

   What happens to the pressure head as fluid exits a pipe?

   Hint

   Refer to the hydraulic gradient line.

2. 2.

   Define a pump in simple terms.

   Hint

   Think about how it works in domestic water supply.

3. 3.

   What does the hydraulic gradient line represent in a fluid system?

   • Energy level
   • Flow velocity
   • Temperature

   Hint

   Think about its relation to pressure and fluid surface.

4. 4.

   True or False: A turbine increases the pressure of a fluid.

   • True
   • False

   Hint

   Consider what happens to energy in a turbine.

5. 5.

   A pipe system incorporates a pump and turbine. If the pump elevates the pressure from 30 psi to 50 psi, while the turbine drops it to 20 psi, calculate the net energy transferred.

   Hint

   Don't forget to convert all pressure units to consistent formats.

6. 6.

   Design a small-scale water system using a pump. What factors would you consider to ensure efficiency?

   Hint

   Think about how each component contributes to the overall efficiency.
