Question

factors affecting fluid friction

Answer 1

hey,,,
____________________________________________________________
Factors that affecting fluid friction are;
1.With increase in temperature, the fluid friction of liquid decreases.
2.The fluid friction of all gases increases with increase in temperature, since the fluid friction of a gas is directly proportional to the square root of the absolute temperature. (This result is obtained from kinetic theory of gases)
3.The fluid friction of liquids increases with increase in pressure. But the fluid friction of water decreases (anomalous behaviour) whereas the fluid friction of gases remain unchanged.

HELLO !!..

HERE IS YOUR ANSWER,

☆▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪▪☆

==> The factors affecting fluid friction are: Material surface roughness 
▪ Viscosity of fluid 
▪ Length of pipe 
▪ Diameter of Pipe 
▪ Flow Rate of fluid 

==> The friction force of an object in a fluid depends on its speed with respect to fluid . It also depends on shape of thee object and nature of the fluid.
