The speed of a liquid flowing through a pipe increases and its pressure decreases when liquid passes through a narrow constriction in the pipe. Why?

If the speed of a liquid flowing horizontally increases at a place, then the quantity that decreases there is

What happeds to the pressure of an ideal liquid when it passes through a region where its speed increases?

The rate of flow (V) of a liquid flowing through a pipe of radius r and pressure gradient (P//I) is given by Poiseuille's equation V = (pi)/(8)(Pr^4)/(etaI) Chack the dimensional correctness of this relation.

An engine pumps liquid of density d continuosly through a pipe of cross-section are A. If the speed with which liquid passes through the pipe is v, then the rate at which kinetic energy is being imparted to the liquid by the pump is

Which of the following device is used to measure the rate of flow of liquid through a pipe?

A pump and its horizontal intake pipe are located 12 m beneath the surface of a reservoir . The speed of the water in the intake pipe causes the pressure there to decrease , in accord with Bernoulli's principle . What is the maximum speed with which water can flow through the intake pipe (assuming non-viscous flow ) ?
