Question

For a viscous fluid flowing in circular pipe the average velocity is 5m/s if the dia of pipe is 0.1 the maximum velocity of fluid at given section is

Answer 1

The instantaneous stream-wise velocity of a turbulent flow is given as follows Consider fully developed flow in a circular pipe with negligible entrance length effects ... if the average flow velocity doubles and the pipe diameter reduces ..iameter 10 cm, velocity 0.1 m/s and kinematic viscosity 10−5 m2/s,

Answer 2

Answer :

The maximum velocity of fluid = 10 m/s

Explanation:

Given data :

The average velocity = 5 m/s

diameter = 0.1 m

Formula to be Used :

The maximum velocity of fluid is twice the the average velocity.

U(maximum) = 2 × U ( average)

U= 2× 5 m/s

U = 10 m/s

Concept :

• Higher viscosity fluids are referred to as viscous fluids.
• The viscous fluids ketchup and honey are examples of.
• Viscous fluid is a term used to describe a fluid that has a high flow resistance.
• The degree of resistance between the fluid layers, or viscosity, is a fluid factor.
• The resistance of a fluid (liquid or gas) to a change in shape or motion of adjacent sections relative to one another is known as viscosity.
• Viscosity is a sign of flow resistance.
