Reynolds number of fluid flowing in Pipe

Go Reynolds Number = (Fluid Velocity*Pipe Diameter*Fluid Density)/Absolute Fluid Viscosity

Flow Rate

Go Volume Flow Rate = Pipe Cross Sectional Area*Fluid Average Velocity

Volume Flow Rate

Go Volume Flow Rate = Mass Flow Rate/Material Density

Mass Flow Rate

Go Mass Flow Rate = Material Density*Volume Flow Rate

Pipe Diameter Formula

Pipe Diameter = (Friction Factor*Pipe Length*Fluid Average Velocity^2)/(2*Head Loss due to Friction*[g])
D = (f*L_p*V_avg^2)/(2*H_f*[g])

Why is it called head loss?

The pressure head is due to the static pressure, the internal molecular motion of a fluid that exerts a force on its container. Resistance head (or friction head or Head Loss) is due to the frictional forces acting against a fluid's motion by the container.
