A horizontal cylindrical vessel with a small orifice of area s is first filled with a liquid of density `rho` and then forced out through it by applying a constant force on the piston closing the cylinder. The time taken is t. The time taken is t. Calculate the work done.

Text Solution

Verified by Experts

The correct Answer is:
`W=(1)/(2)rho(V^(3))/(s^(2)t^(2))`
