4 cards from this section. Quick, good the night before a test.
Define Bernoulli’s equation.
Think about how pressure, velocity, and height are related.
What type of flow is characterized by smooth lines?
Consider whether the fluid moves in an organized fashion.
What does Bernoulli's equation relate in a fluid system?
Think about what factors are involved in fluid dynamics.
True or False: Minor losses have a negligible effect on fluid flow.
Consider how fittings might affect flow.
A pipe with a diameter of 0.2 m has water flowing at a velocity of 3 m/s. If the flow is restricted by a valve with a K-factor of 0.2, calculate the head loss due to this restriction.
Make sure to square the velocity and divide by two times the gravity.
Compare the energy loss between a gate valve and a globe valve with the same diameter with respective K factors of 0.1 and 0.15, given the flow conditions in a directly connected pipe.
Remember to apply the K factors correctly to find relative losses.
