Water flows through cylinder pip of internal diameter 7cm at 2m per second. If the pipe is always half full, them what is the volume of water (in liters) discharged in 10 minutes?
Answered by Steve
the cross-section area of the water is

πd^2/8 = 49π/8

So, the water flowing through is

(49π/8 cm^2)(2m/s)(10min) = 2309 liters
