25.2.1. Energy Transfer in Pump

Try these first

1. 1.

   What is the hydraulic gradient line?

   Hint

   Think about how pressure is distributed in a flowing liquid.

2. 2.

   Identify the purpose of a pitot tube.

   Hint

   What device converts kinetic energy to potential energy for measurement?

3. 3.

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

   • Total energy
   • Pressure head
   • Velocity head

   Hint

   What does this line indicate about fluid pressure?

4. 4.

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

   • True
   • False

   Hint

   Think about the role of turbines in energy extraction.

5. 5.

   A pump increases the pressure of water from 100 kPa to 300 kPa while double the velocity. Using Bernoulli's equation, calculate the potential energy difference involved.

   Hint

   Apply Bernoulli's principles to assess energy differentials.

6. 6.

   In a turbine operating an ideal cycle, the velocity of fluid entering is 5 m/s and exiting 3 m/s. How would this be represented in pressure drop?

   Hint

   Consider how the momentum change relates to energy conservation.
