Cavitation Number Solution

STEP 0: Pre-Calculation Summary
Formula Used
Cavitation number = (Pressure-Vapour Pressure)/(Mass Density*(Fluid Velocity^2)/2)
σc = (p-Pv)/(ρm*(uf^2)/2)
This formula uses 5 Variables
Variables Used
Cavitation number - Cavitation number is used to evaluate weather a fluid system will cause caviation or not.
Pressure - (Measured in Pascal) - Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
Vapour Pressure - (Measured in Pascal) - The Vapour pressure is a measure of the tendency of a material to change into the gaseous or vapour state, and it increases with temperature.
Mass Density - (Measured in Kilogram per Cubic Meter) - The Mass Density of a substance is its mass per unit volume.
Fluid Velocity - (Measured in Meter per Second) - Fluid velocity is the volume of fluid flowing in the given vessel per unit cross sectional area.
STEP 1: Convert Input(s) to Base Unit
Pressure: 800 Pascal --> 800 Pascal No Conversion Required
Vapour Pressure: 6 Pascal --> 6 Pascal No Conversion Required
Mass Density: 997 Kilogram per Cubic Meter --> 997 Kilogram per Cubic Meter No Conversion Required
Fluid Velocity: 12 Meter per Second --> 12 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
σc = (p-Pv)/(ρm*(uf^2)/2) --> (800-6)/(997*(12^2)/2)
Evaluating ... ...
σc = 0.011060960659757
STEP 3: Convert Result to Output's Unit
0.011060960659757 --> No Conversion Required
FINAL ANSWER
0.011060960659757 0.011061 <-- Cavitation number

Equation of Continuity for Compressible Fluids
​ Go Velocity of the fluid at 1 = (Cross-Sectional Area at Point 2*Velocity of the fluid at 2*Density 2)/(Cross-Sectional Area at Point 1*Density 1)
Equation of Continuity for Incompressible Fluids
​ Go Velocity of the fluid at 1 = (Cross-Sectional Area at Point 2*Velocity of the fluid at 2)/Cross-Sectional Area at Point 1
Cavitation Number
​ Go Cavitation number = (Pressure-Vapour Pressure)/(Mass Density*(Fluid Velocity^2)/2)
Bulk Modulus given Volume Stress and Strain
​ Go Bulk Modulus = Volume Stress/Volumetric Strain

Cavitation Number Formula

Cavitation number = (Pressure-Vapour Pressure)/(Mass Density*(Fluid Velocity^2)/2)
σc = (p-Pv)/(ρm*(uf^2)/2)

What is cavitation number?

The Cavitation number (Ca) is a dimensionless number used in flow calculations. It expresses the relationship between the difference of a local absolute pressure from the vapor pressure and the kinetic energy per volume, and is used to characterize the potential of the flow to cavitate.
