What is the critical velocity for a non viscous liquid?
This is actually a very difficult problem to solve, as the critical velocity of liquid flow is the point where the flow changes from laminar to turbulent. A Reynolds Number of 2320 or less defines laminar flow, and higher than that 4000 defines turbulent flow. Here, the fluid is specified to be non-viscous.
What is critical velocity in viscosity?
The critical velocity depends on coefficient of viscosity η, density of the liquid d, and radius of the tube r as given by. Vc=drkη where k is the constant of proportionality.
What is critical velocity of a fluid?
Definition of critical velocity : the greatest velocity with which a fluid can flow through a given conduit without becoming turbulent.
What are the characteristics of a non viscous fluid?
Non-viscous fluids are classified as fluids that have no resistance or negligible resistance to internal friction.
How do you find the critical velocity?
If you wanted to find the critical velocity for water moving through a section of pipe, we’ll start out by using the basic formula for calculating critical velocity: Vcrit = (Nr_µ) / (D_ρ).
What is critical velocity write the formula for the critical velocity?
Vc=rkηd
What is critical velocity obtain an expression for critical velocity?
The expression for critical velocity: Let M be the mass of the Earth and R be its radius. If the satellite is moving in a circular orbit of radius (R + h) = r, its speed must be equal to the magnitude of critical velocity vc.
What is non viscosity?
A non-Newtonian fluid is a fluid that does not follow Newton’s law of viscosity, i.e., constant viscosity independent of stress. In non-Newtonian fluids, viscosity can change when under force to either more liquid or more solid. The fluid can even exhibit time-dependent viscosity.
What is the difference between viscosity and viscous force?
The property of a fluid due to which it opposes the relative motion between its different layers is called viscosity and the force between the layers opposing the relative motion is called viscous force.
What do you mean by critical velocity of a liquid derive an expression for it on the basis of dimensional considerations?
⇒ Dimensional formula of Coefficient of viscosity, (η) = [M^1 L^(-1) T^(-1)] ⇒ Dimensional formula of radius, (r) = [L^1] ⇒ Dimensional formula of critical velocity, (V) = [M^0 L^1 T^(-1)] ⇒ V = [M^1 L^(-3)]^a. [
What is critical velocity obtain?
If the escape velocity on earth is 11. 2km/sec, its value for a planet having double the radius and 8 times the mass of earth is ….. m/sec.
