What is the equation for fluid dynamics?
Flow rate and velocity are related by Q=Av Q = A v where A is the cross-sectional area of the flow and v is its average velocity. The equation of continuity states that for an incompressible fluid, the mass flowing into a pipe must equal the mass flowing out of the pipe.
What is the formula for fluid friction?
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.
How do you calculate power fluid?
Power in fluid flow is given by the equation (P1+12ρv2+ρgh)Q=power, ( P 1 + 1 2 ρ v 2 + ρ gh ) Q = power , where the first term is power associated with pressure, the second is power associated with velocity, and the third is power associated with height.
How do you calculate H in fluid mechanics?
Pressure due to the weight of a liquid of constant density is given by p=ρgh p = ρ g h , where p is the pressure, h is the depth of the liquid, ρ is the density of the liquid, and g is the acceleration due to gravity.
What is fluid friction short answer?
Fluid friction is a force that restricts the movement either within itself or of another medium moving through the liquid. It describes the friction between the layers of the viscous liquid that moves relative to each other. The internal resistance to flow is termed as viscosity.

What is the formula for pressure in fluids?
Fluid Pressure Formula I m a g e w i l l b e U p l o a d e d S o o n The following relation can be used to calculate the pressure in fluids. Pfluid = P + ρgh
What is the pressure head of a fluid?
The pressure head is given by the formula: The pressure head in fluid mechanics can be determined by considering the pressure acting at any point on a fluid in rest condition. As per the hydrostatic law, the rate of increase of pressure in the vertically downward direction must be equal to the specific weight of the fluid at that point.
What is the formula for discharge in fluid mechanics?
The amount of fluid passing a section of a stream in unit time is called the discharge. If v is the mean velocity and A is the cross sectional area, the discharge Q is defined by Q = Av which is known as volume flow rate. Discharge is also expressed as mass flow rate and weight flow rate.
What is the hydrostatic pressure of a fluid?
The hydrostatic pressure is the pressure exerted by a fluid at equilibrium at any point of time due to force of gravity. Firstly solid objects do not change their shape on the application of pressure which is obviously not the case with fluids. Fluid pressure can be caused by gravity, acceleration or forces when in a closed container.
