An irrigation canal has a rectangular cross section. at one point whare the canal is 16.0 m wide, and the water is 3.8 m deep, the water flow is 2.8 cm/s. at a second point downstream, but on the same level, the canal is 16.5 m wide, but the water flows at 11.0 cm/s. how deep in meters is the water at this point?

The depth of the water at this point is 0.938 m.

Explanation:

Given that,

At one point

Wide= 16.0 m

Deep = 3.8 m

Water flow = 2.8 cm/s

At a second point downstream

Width of canal = 16.5 m

Water flow = 11.0 cm/s

We need to calculate the depth

Using Bernoulli theorem

Put the value into the formula

Hence,  The depth of the water at this point is 0.938 m.
