F_v = A*V_avg
This formula uses 3 Variables

Variables Used

Volume Flow Rate - (Measured in Cubic Meter per Second) - Volume flow rate is the quantity of fluid that passes through a given point or area in a system over a specific period of time.
Pipe Cross Sectional Area - (Measured in Square Meter) - Pipe Cross Sectional Area is the internal surface area through which a fluid flows, perpendicular to the direction of flow.
Fluid Average Velocity - (Measured in Meter per Second) - Fluid Average Velocity is the mean speed at which fluid particles travel through a cross-section of a conduit, influencing flow rate and dynamics, typically measured in meters per second (m/s).

STEP 1: Convert Input(s) to Base Unit

Pipe Cross Sectional Area: 0.36 Square Meter --> 0.36 Square Meter No Conversion Required

Drag Coefficient of Pipe

Go Drag Coefficient = (Force Flow*2*[g])/(Specific Weight Fluid Flow*Pipe Cross Sectional Area*Fluid Velocity)

Length of Pipe

Go Pipe Length = (2*Pipe Diameter*Head Loss due to Friction*[g])/(Friction Factor*Fluid Average Velocity^2)

Pipe Diameter

Go Pipe Diameter = (Friction Factor*Pipe Length*Fluid Average Velocity^2)/(2*Head Loss due to Friction*[g])

Head Loss

Go Head Loss due to Friction = (Friction Factor*Pipe Length*Fluid Average Velocity^2)/(2*Pipe Diameter*[g])

Density of Liquid

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

Reynolds number of fluid flowing in Pipe

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