A water tank is placed on a platform of height 5 m high and there is an orifice near the bottom in the wall of tank at 5 m below the level of water. Find the speed with which water will hit the ground [Take g = 10 m/`s^(2)` ]

Text Solution

Verified by Experts

The. velocity of efflux = `sqrt(2gh)`
`sqrt(2xx10xx5)`
10m/s
The motion of liquid in horizontal direction is uniform
`:. V_(x) = sqrt(2gh) = `10 m/s
For vertical motion `v_(Y) = sqrt(2gh) ` 10 m/s
`:. V = sqrt(v_(x)^(2) + V_(Y)^(2)) = sqrt((10)^(2) + 10^(2))` = `sqrt(200)`
v = `14.14` m/s
