Variables Used
Pressure Difference in Viscous Flow - (Measured in Pascal) - The Pressure Difference in Viscous Flow or the laminar flow is known to find the difference between initial and final pressure.
Viscosity of Fluid - (Measured in Pascal Second) - The Viscosity of fluid is a measure of its resistance to deformation at a given rate.
Average Velocity - (Measured in Meter per Second) - Average Velocity is defined as the mean of all different velocities.
Length of Pipe - (Measured in Meter) - Length of Pipe refers to the distance between two points along the pipe's axis. It is a fundamental parameter used to describe the size and layout of a piping system.
Pipe Diameter - (Measured in Meter) - Pipe Diameter is the diameter of the pipe in which the liquid is flowing.

What is viscous flow?

A type of fluid flow in which there is a continuous steady motion of the particles; the motion at a fixed point always remains constant. Also called streamline flow; laminar flow; steady flow.

What is pressure drop?

Pressure drop is defined as the difference in total pressure between two points of a fluid carrying network. A pressure drop occurs when frictional forces, caused by the resistance to flow, act on a fluid as it flows through the tube.

How to Calculate Difference of Pressure for Viscous or Laminar Flow?

Difference of Pressure for Viscous or Laminar Flow calculator uses Pressure Difference in Viscous Flow = (32*Viscosity of Fluid*Average Velocity*Length of Pipe)/(Pipe Diameter^2) to calculate the Pressure Difference in Viscous Flow, Difference of Pressure for Viscous or Laminar Flow often described by the Hagen-Poiseuille equation, depends on the fluid's viscosity, the length and radius of the pipe, and the flow rate.
