The foot valve of lift pump is placed in the piston.` "____________"`

The two valves of Unio are hinged

Valve of Thebesius is present at the opening of

Valves occur in

The mitral valve is supported by :-

The valve of Poisson's ratio lies between

A pump is designed as a horizontal cylinder with a piston of area A and and outlet orifice of area a arranged near 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 .

Two pistons of a hydraulic machine have diameters 20 cm and 2 cm. Find the force exerted on the larger piston when 50 kg wt is placed on the smaller piston. When the smaller piston moves is throught 50 cm, by what distance the other piston moves out ?

What are pumps ?

When the piston of common water pump is raised its piston valve opens.

The period of a piston in an engine, moving simple harmonically is 2 s. A body of mass 10 kg is placed on the piston. Calculate the maximum amplitude of the piston such that the mass is not thrown out from the platform.
