Variables Used

Pressure Gradient - (Measured in Newton per Cubic Meter) - The Pressure Gradient refers to the rate of change of pressure in a particular direction indicating how quickly the pressure increases or decreases around a specific location.
Mean Velocity - (Measured in Meter per Second) - Mean velocity is defined as the average velocity of a fluid at a point and over an arbitrary time T.
Horizontal Distance - (Measured in Meter) - Horizontal Distance denotes the instantaneous horizontal distance cover by an object in a projectile motion.
Width - (Measured in Meter) - The Width refers to the measurement or extent of something from side to side.
Flow velocity - (Measured in Meter per Second) - Flow Velocity is the velocity of the flow of any fluid.
Dynamic Viscosity - (Measured in Pascal Second) - The Dynamic Viscosity refers to the internal resistance of a fluid to flow when a force is applied.

STEP 1: Convert Input(s) to Base Unit

Mean Velocity: 10.1 Meter per Second --> 10.1 Meter per Second No Conversion Required
Horizontal Distance: 4 Meter --> 4 Meter No Conversion Required
Width: 2.29 Meter --> 2.29 Meter No Conversion Required
Flow velocity: 46.8 Meter per Second --> 46.8 Meter per Second No Conversion Required
Dynamic Viscosity: 10.2 Poise --> 1.02 Pascal Second (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

dp|dr = ((V_mean*R/w)-V_f)/(((0.5*(w*R-R^2))/μ)) --> ((10.1*4/2.29)-46.8)/(((0.5*(2.29*4-4^2))/1.02))
