What is fluid friction coefficient?
Fluid friction is the force that resists motion either within the fluid itself or of another medium moving through the fluid. There is internal friction, which is a result of the interactions between molecules of the fluid, and there is external friction, which refers to how a fluid interacts with other matter.
What is Q in friction?
Where FL = Friction Loss in PSI, C = friction loss Coefficient (or friction loss factor), Q = Flow rate in GPM, and L = hose Length.
What is fluid friction formula?
When an object moves through a fluid with velocity v, presenting area A to the fluid, the molecules that bounce off the object transfer momentum to the object at rate Δp/Δt = F, where F is the resulting drag force.
What is mu s in physics?
The coefficient of static friction is assigned the Greek letter “mu” (μ), with a subscript “s”. The maximum force of static friction is μs times the normal force on an object.
What is fluid friction write the factors on which fluid friction depends?
Answer. Fluid friction is the force that resists motion either within the fluid itself or another medium moving through the fluid. Fluid friction depend on an object speed with respect to the fluid . The fluid friction also depends on the shape of the object and the nature of the fluid.
What is the coefficient for 3 hose?
0.677
Answer: There’s 69.75 PSI friction loss for a 200 foot of 1.75 inch hose with 150 GPM….Example:
| Coefficient Table | |
|---|---|
| Diameter | Coefficient |
| 2 ½ inch | 2 |
| 3 inch | 0.677 |
| 3 ½ inch | 0.34 |
What does a lower coefficient of friction mean?
The coefficient of friction, µ, is a measure of the amount of friction existing between two surfaces. A low value of coefficient of friction indicates that the force required for sliding to occur is less than the force required when the coefficient of friction is high.
What is fluid friction Class 9?
Fluid friction is a force that restricts the movement either within itself or of another medium moving through the liquid. Due to the movement of the molecules inside the fluid, internal friction occurs, and how the fluid interacts with other matter, external conflict occurs.
What is fluid friction Class 11?
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
How do you find coefficient of friction?
The formula to calculate the coefficient of friction is μ = f÷N. The friction force, f, always acts in the opposite direction of the intended or actual motion, but only parallel to the surface.
