Conversion Factor given Flow Velocity

Go Conversion factor = ((Flow Velocity*Roughness Coefficient of Conduit Surface)/((Energy loss^(1/2))*Hydraulic Radius^(2/3)))

Hydraulic Radius given Flow Velocity

Go Hydraulic Radius = ((Flow Velocity*Roughness Coefficient of Conduit Surface)/(Conversion factor*Energy loss^(1/2)))^(3/2)

Roughness Coefficient using Flow Velocity

Go Roughness Coefficient of Conduit Surface = (Conversion factor*Hydraulic Radius^(2/3)*Energy loss^(1/2))/Flow Velocity

Flow Velocity using Manning's formula

Go Flow Velocity = (Conversion factor*Hydraulic Radius^(2/3)*Energy loss^(1/2))/Roughness Coefficient of Conduit Surface

Energy Loss given Flow Velocity

Go Energy loss = ((Flow Velocity*Roughness Coefficient of Conduit Surface)/(Conversion factor*Hydraulic Radius^(2/3)))^2

Velocity using Water Flow Equation

Go Flow Velocity = Water Flow/Cross-Sectional Area

Area given Water Flow Equation

Go Cross-Sectional Area = Water Flow/Flow Velocity

Water Flow Equation

Go Water Flow = Cross-Sectional Area*Flow Velocity

Water Flow Equation Formula

Water Flow = Cross-Sectional Area*Flow Velocity
Q = A_cs*V_f

What is the difference between flow rate and velocity?

Rate of flow, or simply flow, is the quantity of water, for example, that flows in a tube or other medium, in an interval of time. Examples: 2 kg of water per second, or 100 cubric meters of air per minute. Velocity is how fast the water, air or other fluid is moving in a tube or other medium.
