3 cards from this section. Quick, good the night before a test.
What is a hydraulic gradient line?
Consider where the free surface of the liquid is.
Explain the role of a pump in a fluid system.
Think about the direction of energy transfer.
What does the hydraulic gradient line represent?
Think about what you measure at the free surface.
False or True: A turbine decreases fluid pressure by converting mechanical energy into fluid energy.
Consider the direction of energy transfer.
A pump rated at 2000 Watts boosts water pressure from 50 kPa to 150 kPa. Calculate the water flow rate if the pump is 80% efficient.
Consider how much energy is actually being used after accounting for efficiency.
Using Bernoulli’s equation, calculate the velocity of water flowing through a pipe at point A with a pressure of 80 kPa, at an elevation of 5 m, if at point B the pressure is 40 kPa with a height of 2 m.
Ensure elevation differences and pressure changes are reflected correctly.
