Critical velocity of the liquid

What is meant by critical velocity of a liquid? Explain the characteristic of turbulent motion.

Select the correct pair of reasons for the following statements. Critical velocity of liquid decreases when:

If dimensions of critical velocity of a liquid v_c flowing through a tube are expressed as [eta^xrho^yr^z] , where eta , rho and r are the coefficient of viscosity of liquid, density of liquid and radius of the tube respectively, then the values of x , y and z are given by :

What is meant by critical velocity of a liquid?

What do you mean by critical velocity of a liquid?Derive an expression for it on the basis of dimensional considerations.

Critical velocity of the orbiting satellite is, independent of

The critical velocity v for a liquid depends upon (a) coefficient of viscosity eta (b) density of the liquid rho and © radius of the pipe r. Using dimensions derive an expression for the critical velocity.

The critical velocity of the flow of a liquid through a pipe of radius 3 is given by v_c= (K eta/rp) , where p is the density and eta , is the coefficient of viscosity of liquid. Check if this relation is dimentionally correct.
