Question

The hydraulic mean depth for a circular pipe of diameter 'd' running full is equal to

Answer 1

Hello Dear,

◆ Answer -

Hydraulic mean depth = d/4

◆ Explaination -

Hydraulic mean depth of a pipe is given by -

Hydraulic mean depth = cross-sectional area / perimeter of pipe

For circular pipe,

Cross-sectional area = πr² = πd²/4

Perimeter of pipe = 2πr = πd

So substitute these values -

Hydraulic mean depth = (πd²/4) / (πd)

Hydraulic mean depth = d/4

Therefore, Hydraulic mean depth of a circular pipe is d/4.

Thanks dear...
