At what speed will the velocity head of stream of water be

40 \mathrm{~cm}

?

View answer and explanation

Correct option: A

280 \mathrm{~cms}^{-1}

Option A (

280 \mathrm{~cms}^{-1}

) is correct because it is the speed calculated using the formula

v = \sqrt{2gh}

with the given velocity head.
