Water in a canal is flowing at a rate of 3 km per hour. It is 4 m deep and 15 m wide. How much water will fall into the land to be irrigated in half an hour?

Expert Answer:

Depth of the canal (h) = 4 m, Width of the canal (b) = 15 m

Water is flowing at the rate of 3 km/hr or 3000 m/hr.

In 1 hour, water flowing through the tank = 3000 x 4 x 15 m3 = 180000 m3

Thus, in half an hour, water flowing through the tank = 90000 m3 = 90 Kl.
