Water flows at 5 m3 /s in a 1 m × 2 m rectangular concrete pipe. Calculate the head loss over a length of 100 m.

Water flows at 10 m3 /s in a 2 m × 2 m square reinforced concrete pipe. If the pipe is laid on a (downward) slope of 0.002, what is the change in pressure in the pipe over a distance of 500 m?
