On the opposite sides of a wide vertical...

On the opposite sides of a wide vertical vessel filled with water, two identical holes are opened, each having cross section area a. The height difference between them is equal to `h`. Find the resultant force of reaction of water flowing out of vessel.

Text Solution

Verified by Experts

`F=2rhogAhd`
`F-vxx(dm)/(dt)=vxxrhoa(de)/(dt)=rhoav^(2)`
Reaction force by the efflux of the vessel.
`F=rhoav^(2),v=sqrt(2gh)=rhoa2gh,F=2rhoagh`
`F_(net)=rhoa2g(h_(1)-h_(2))=rhoa2gDeltah`
