WASTEWATER By Rick Lallish
In pump hydraulics, what condition is a measurement of the physical vertical distance between the surfaces of two fluids, but is not related to how far the fluids are apart horizontally?
A. Specific gravity
B. Lift
C. Static head
D. Dynamic head
Answer: C. Static head is the physical vertical distance between the surfaces of two fluids no matter the physical distance apart horizontally. Dynamic head is the theoretical distance rather than the physical distance. Both conditions are measured in feet of head.
