If the velocity head of a stream of water is equal to 10 cm, then its speed of flow is approximately

A

`1.0ms^(-1)`

B

`1.4ms^(-1)`

C

`140 ms^(-1)`

D

`10ms^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
B
Given , `(v^2)/(2g)=h=10cm`
`therefore v=sqrt(2gh) = sqrt(2xx10xx0.1) =sqrt(2) ms^(-1)`
`=1.414ms^(-1)`
