1.	A pump draws water from a reservoir and sends it through a horizontal pipe with speed v. Find the relation between power of the pump and velocity of liquid.
Answer» <P> Solution :From work - ENERGY theorem `P=(KE "imparted to water")/("TIME")` `=(KE)/("volume of water")xx("volume of water")/("time")` `=(1/2rhov^(2))(AV)` or `P PROP v^(3)`
