## Cavitation Number Solution

STEP 0: Pre-Calculation Summary
Formula Used
cavitation_number = (Pressure-Vapour Pressure)/(mass density*(Fluid Velocity^2)/2)
σc = (P-Pv)/(ρ*(uf^2)/2)
This formula uses 4 Variables
Variables Used
Pressure - The pressure is defined as the physical force exerted on an object. It is symbolized by P. (Measured in Pascal)
Vapour pressure - 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. (Measured in Bar)
mass density - The mass density of a substance is its mass per unit volume (Measured in Kilogram per Meter³)
Fluid Velocity - Fluid velocity is the volume of fluid flowing in the given vessel per unit cross sectional area. (Measured in Meter per Second)
STEP 1: Convert Input(s) to Base Unit
Pressure: 800 Pascal --> 800 Pascal No Conversion Required
Vapour pressure: 1 Bar --> 100000 Pascal (Check conversion here)
mass density: 1000 Kilogram per Meter³ --> 1000 Kilogram per Meter³ No Conversion Required
Fluid Velocity: 1 Meter per Second --> 1 Meter per Second No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
σc = (P-Pv)/(ρ*(uf^2)/2) --> (800-100000)/(1000*(1^2)/2)
Evaluating ... ...
σc = -198.4
STEP 3: Convert Result to Output's Unit
-198.4 Percentage -->-198.4 ISO (Check conversion here)
-198.4 ISO <-- Cavitation number
