## Volumetric flow rate of circular orifice Solution

STEP 0: Pre-Calculation Summary
Formula Used
volumetric_flow_rate = 0.62*Area of orifice*sqrt(2*Acceleration Due To Gravity*Head)
V = 0.62*a*sqrt(2*g*H)
This formula uses 1 Functions, 3 Variables
Functions Used
sqrt - Squre root function, sqrt(Number)
Variables Used
Area of orifice - The Area of orifice is often a pipe or tube of varying cross-sectional area, and it can be used to direct or modify the flow of a fluid (liquid or gas). (Measured in Square Meter)
Acceleration Due To Gravity - The Acceleration Due To Gravity is acceleration gained by an object because of gravitational force. (Measured in Meter per Square Second)
Head - Head is defined as the height of water columns. (Measured in Meter)
STEP 1: Convert Input(s) to Base Unit
Area of orifice: 10 Square Meter --> 10 Square Meter No Conversion Required
Acceleration Due To Gravity: 9.8 Meter per Square Second --> 9.8 Meter per Square Second No Conversion Required
