Venturi Meter Experiment Calculations

Venturi Meter Experiment Calculations: A Comprehensive Guide

Introduction & Importance

Venturi meter experiment calculations are crucial in fluid dynamics, enabling the measurement of flow rates and pressure differences. Understanding these calculations is vital for designing and optimizing fluid systems.

How to Use This Calculator

1. Enter the diameter of the venturi meter.
2. Enter the velocity of the fluid.
3. Enter the pressure at the venturi meter’s throat.
4. Click ‘Calculate’.

Formula & Methodology

The formula for calculating the flow rate (Q) using a venturi meter is:

Q = A * V * sqrt((2 * (P1 – P2)) / ρ)

Where:

• A is the cross-sectional area of the venturi meter’s throat.
• V is the average velocity of the fluid at the throat.
• P1 is the pressure at the inlet.
• P2 is the pressure at the throat.
• ρ is the density of the fluid.
