If pump head is 60 ft and system losses are 25 ft, what is net pump head?

Explanation:
Net pump head equals the head the pump adds minus the losses incurred in the system. The pump provides 60 ft of head, while the piping and fittings cause 25 ft of losses. Subtracting gives 60 ft − 25 ft = 35 ft. So the net pump head is 35 ft. If you ignored losses you’d get 60 ft, if you added losses you’d get 85 ft, and if you only counted the losses you’d have 25 ft.
