Q: What can you add to a pump to prevent it from dry-running?
A: Nothing, you can only use pumps with built-in dry-running protection
Q: What does friction loss refer to?
A: A rapid decrease of flow and increase of pressure
Q: What does friction loss refer to?
A: The formation of air bubbles in the moving liquid
Q: What does friction loss refer to?
A: Contact between the moving liquid and its enclosure
Q: Why is it an advantage to mount your pump to a fixed base?
A: A steady pump operates more efficiently
