From a horizontal tube with area of cross-section `A_(1)` and `A_(2)` as shosn in fiugre liquid is flowing in the level of the liauid in the two veritcal tunes is h.

A

The volume of the liquid flowing through the tube in time is `A_(1)v_(1)`

B

`v_(2)-v_(1)=sqrt(2gh)`

C

`v_(2)^(2)-v_(1)^(1)=2gh`

D

The energy per unit mass of the liquid is the same in both sections of the tube

Text Solution

Verified by Experts

(c) `(p_(1))/(rho)+(v_(1)^(2))/(2)=(p_(2))/(rho)+(v_(2)^(2))/(2)`
or` " " p_(1)-p_(2)=(rho)/(2)(v_(2)^(2)-v_(1)^(2))`
But `" " p_(1)-p_(2)=rhogh=(rho)/(2)(v_(2)^(2)-v_(1)^(2))`
or `" " v_(2)^(2)-v_(1)^(2)=2gh`
