PHYIC CALCULATOR
Venturi Effect Calculator
A precise tool.
What is the Venturi Effect Calculator & How does it work?
The Venturi effect is the phenomenon where a fluid flowing through a constricted section of a pipe experiences an increase in velocity and a corresponding decrease in pressure. This principle is based on the continuity equation and Bernoulli’s equation.
A_1v_1 = A_2v_2
A = cross-sectional area, v = velocity
Bernoulli’s equation relates the pressure and velocity of a fluid:
P_1 + frac{1}{2}rho v_1^2 = P_2 + frac{1}{2}rho v_2^2
P = pressure, rho = density of the fluid

Frequently Asked Questions
What is the Venturi effect?
The Venturi effect describes how a fluid’s velocity increases as it passes through a constricted section of a pipe, resulting in a decrease in pressure.
How does the continuity equation apply to the Venturi effect?
The continuity equation states that the product of cross-sectional area and velocity is constant (A_1v_1 = A_2v_2), meaning as the area decreases, velocity increases.
What does Bernoulli’s equation tell us about fluid flow in a Venturi meter?
Bernoulli’s equation relates pressure and velocity, showing that an increase in velocity results in a decrease in pressure (P_1 + 1/2Οv_1^2 = P_2 + 1/2Οv_2^2).
How can I use this calculator to find the velocity of fluid at different sections?
Input the cross-sectional areas and pressure values for both sections into the calculator, and it will compute the velocities based on the Venturi effect principles.
What are some practical applications of the Venturi effect?
The Venturi effect is used in flow measurement devices like flow meters, atomizers, and carburetors to control fluid flow rates accurately.
How does density affect the results in a Venturi meter calculation?
Density (Ο) is a crucial factor in Bernoulli’s equation; changes in fluid density will directly impact the calculated pressure differences and velocities.
Can this calculator handle gases as well as liquids?
Yes, the Venturi effect applies to both gases and liquids. However, ensure that the gas behaves ideally or use specific equations of state for more accurate results.
