A pump is designed as a horizontal cylinder with a piston of areal `A` and and outlet orifice of areal a arranged mear the cylinder axis. Find the velocity of out flow of the liquid from the pump if the piston moves with a constant velocity under the action of a constant force F. The density of the liquid is `rho`.

Answer

A, B

Explanation

`p_(1)+1/2rhov_(1)^(2)=p_(2)+1/2rhov_(2)^(2)`
` (p_(0)+(F)/(A)) +0= p_(0) +(1)/(2) rhov^(2)`
`:. v = sqrt((2F)/(rhoA))`
