Question

Calculate the discharge (in cubic meters/second) if a large stream's average velocity is 3 meters/second, its stage is 14 meters, and its width as measured bank-to-bank is 27 meters.

Answer 1

Step-by-step explanation:

Given

average velocity of stream is
`v_(avg)=3\ m/s`

Stage of stream i.e. depth
`d=14\ m`

width of stream
`w=27\ m`

We know that discharge of a stream is given by

`Q=A\cdot v`

where A=area of cross-section

v=average velocity

`A=14* 27\ m^2`

Therefore discharge is given by

`Q=14* 27* 3`

`Q=1134\ m^3/s`
