ONE FORMULA, ONE ANSWER
Plane Couette Flow Drag Force Calculator
Calculate the viscous drag-force magnitude on one face of a moving plate from the linear velocity profile between parallel plates. Choose input units and calculate one value within the stated conditions.
Inputs
Calculations run in this browser. Scientific notation such as 1.2e-3 is supported. Do not group thousands.
Result
Viscous drag-force magnitude on the moving plate
Enter values and select Calculate.
F = μAV / h
Assumptions
Required: steady laminar incompressible Newtonian flow with one stationary plate, one steadily moving plate, and constant dynamic viscosity. Excluded: pressure gradient, wall slip and edge effects. The result is the magnitude of drag opposing plate motion.
Displayed values are floating-point approximations. Design safety factors and unprovided error contributions are not calculated.
