Pipe Diameter

Go Diameter of Pipe = (Friction Factor*Length of Displacer*(Average Velocity^2))/(2*Head Loss Due to Friction*Acceleration Due to Gravity)

Length of Pipe

Go Length of Pipe = Diameter of Pipe*(2*Head Loss due to Friction*Acceleration due to Gravity)/(Friction Factor*(Average Velocity^2))

Head Loss

Go Head Loss due to Friction = (Friction Factor*Length of Pipe*(Average Velocity^2))/(2*Diameter of Pipe*Acceleration due to Gravity)

Drag Coefficient of Pipe

Go Drag Coefficient = Force*(2*Acceleration Due to Gravity)/(Specific Weight Fluid*Area of Cross-Section*Velocity of Fluid)

Reynolds number of fluid flowing in Pipe

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

Absolute Viscosity

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

Absolute Viscosity Formula

Absolute Viscosity of Fluid = (Velocity of Fluid*Diameter of Pipe*Density of Fluid)/Reynolds Number
µ_a = (V*D*ρ)/R

Does high viscosity mean thick?

In layman's terms, viscosity defines a fluid's resistance to flow. The higher the viscosity of a liquid, the thicker it is and the greater the resistance to flow. The temperature will affect the viscosity of most materials.
