Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Formulas to find Reynolds Number

Fluid Velocity

Fluid Velocity is the speed and direction at which fluid particles move through a given point, influencing flow dynamics and rate, typically measured in meters per second (m/s).

Symbol: V

Measurement: SpeedUnit: m/s

Note: Value should be greater than 0.

Formulas to find Fluid Velocity

Pipe Diameter

Pipe Diameter is the width of a cylindrical conduit, crucial in fluid dynamics, influencing flow rate, pressure drop, and system design, typically measured in millimeters or inches.

Symbol: D

Measurement: LengthUnit: m

Note: Value should be greater than 0.

Formulas to find Pipe Diameter

Fluid Density

Fluid Density is the mass per unit volume of a fluid, influencing buoyancy, pressure, and flow behavior, typically measured in kilograms per cubic meter (kg/m³).

Symbol: ρ

Measurement: DensityUnit: kg/m³

Note: Value should be greater than 0.

Formulas to find Fluid Density

Absolute Fluid Viscosity

Absolute Fluid Viscosity is a measure of a fluid's resistance to flow. It quantifies internal friction, affecting how smoothly fluid layers slide past one another under an applied force.
