Question

At same pressure and in same tube oil flow
is lesser than water flow due to
fa) Oil has less density than water.
(b) Oil has greater viscosity than water.
(c) Water has less density than oil
(d) None of these​

Answer 1

Answer:

oil has less density than that of water

Answer 2

Oil flow is lesser due to the reason -

(b) Oil has greater viscosity than water

•Viscosity of a fluid is defined as the resistance in flow of liquid.

•In liquids, factor responsible for viscosity is cohesive force.

•Cohesive force is the force that occurs between molecules of entities of same kind.

•Since, it is a well known fact that viscosity of oil is greater than water, thus it causes resistance to movement of oil, making its flow lesser.
