Water falls from a tap,down the streamline. What happens to the cross-sectional area of the water stream?

Give an example of steady flow.

An engine pump ejects a liquid of density $\rho$ through a pipe of cross-sectional area $A$. If the velocity of the liquid coming out of the pipe is $v$,find the rate at which kinetic energy is imparted to the liquid.

$A$ gardening pipe having an internal radius '$R$' is connected to a water sprinkler having '$n$' holes each of radius '$r$'. The water in the pipe has a speed '$v$'. The speed of water leaving the sprinkler is

An incompressible liquid flows through a horizontal tube as shown in the following figure. Then the velocity $v$ of the fluid is ....... $m/s$.

The Bhagirathi and the Alaknanda merge at Deoprayag to form the Ganga. The speeds of the Bhagirathi and the Alaknanda are in the ratio $1: 1.5$. The cross-sectional areas of the Bhagirathi,the Alaknanda,and the Ganga are in the ratio $1: 2: 3$. Assuming streamline flow,the ratio of the speed of the Ganga to that of the Alaknanda is
