1
Q
Simplifeid __ __ for water pumping
A
Horse Power
Brake horse power = pressure * flow
or
Head (in feet) * GPM / 3960 * pump efficiency
2
Q
You can reduce energy by reducing __ or __
A
head or flow
3
Q
__ is when a pump is restricting the outlet flow of a pump by partially closing a valve
A
throttling
4
Q
Affinity Laws to calculate savings
A
Power 2 / power 1 = flow 2 / flow 1
5
Q
What can you install to make air compressors more efficient?
A
Pressure buffer
prevents excessive cycling of load/unload compressors
