Mechanical & Fluids Diagnose a problem
Why a pump is cavitating and what NPSH margin it needs

Mechanical & Fluids Calculate a value
Measuring flow over a weir, and knowing when the reading is wrong
Converting head over a crest to discharge for common weir shapes, and the conditions that invalidate the reading.

Plumbing & Fire Diagnose a problem
Sizing a sump pump for the storm that will actually arrive
Converting drainage area and rainfall intensity into inflow, then applying the margin a real storm will need.
