A bilge pump rated at 1,500 GPH at zero head will deliver how much flow at 1 meter of head?
-
A
Approximately 1,500 GPH — head does not affect output
-
B
Significantly less than 1,500 GPH due to increased resistance
-
C
More than 1,500 GPH because pressure assists flow
-
D
Exactly 750 GPH regardless of pump type
