The sides of a horizontal pipe carrying dirty water get dirty. Explain.

Explain why, iron pipes for carrying water are coated with zinc.

A horizontal pipe carries water in the positive direction of x. Small identical holes are made at three different places along the pipe such that streams of water from them come out vertically upwards. The height upto which the water stream rise from the three holes

To prevent corrosion, iron pipes carrying drinking water are covered with zinc. The process involved is

Water flows through a horizontal pipe of varying area of cross section at the rate 15 cubic metre per minute. Find the radius of pipe where water velocity is 3 ms^(-1)

Water flows through a horizontal pipe of varying area of cross-section at the rate of 10 cubic metre per minute. Determine the velocity of water at a point where radius of pipe is 10cm.

Water flows through a horizontal pipe of varying area of cross-section at the rate 5 cubic metre per minute. What is the velocity of water at a point where pipe radius is 10 cm?

Lead pipes are not used for carrying drinking water because

What flows through a horizontal pipe of radius r at a speed V. if the radius of the pipe is doubled, the speed of flow of water under similar conditions is
