Explanation Given data: The radius of the tube is R , length is l , average temperature of water is T ° C , and the flow rate of water is Q cm 3 /s . Formula used: Write Poiseuille’s law. P 1 − P 2 = ( 8 π ) η l r 4 Q Here, P 1 − P 2 is the fluid’s forward pressure difference, η is the viscosity of the fluid, l is the length of flow, r is the radius of hose, and Q is the flow rate. Explanation: Whenever a fluid flows through a hose, it experiences a resistance in the opposite direction. This resistance causes a pressure drop in the fluid, which depends upon four factors, namely viscosity of fluid, length of the hose, radius of the hose, and flow rate. Poiseuille’s law defines the relation between these 4 factors and the viscous pressure of the fluid

Viscosity

The measure of the resistance of a fluid to flow is known as viscosity. Most fluids have some resistance to motion, the resistance provided by the fluid is called viscosity. This resistance is created by the force of attraction between the fluid molecule…
