Bernoulli Equation Calculator (Solve for Mass and Volume Flow Rate)


Fluid dynamics is a fascinating field that plays a crucial role in various engineering and physics applications. Understanding the behavior of fluids, whether it’s air, water, or any other liquid or gas, is essential for solving real-world problems. One fundamental concept in fluid dynamics is the Bernoulli Equation, a powerful tool that relates pressure, fluid density, fluid velocity, and height in a fluid flow system. To simplify the calculations related to this equation, we have developed a Bernoulli Equation Calculator. In this article, we will explore how to use this calculator effectively, provide you with the formula, a practical example, answer some common questions, and offer a conclusion that sums up the benefits of using this tool.

How to Use

To utilize the Bernoulli Equation Calculator, follow these simple steps:

Step 1: Input Parameters

  • Pressure (Pa): Enter the pressure in Pascals (Pa) at the desired point in the fluid flow system.
  • Fluid Density (kg/m³): Specify the density of the fluid in kilograms per cubic meter (kg/m³).
  • Fluid Velocity (m/s): Provide the velocity of the fluid in meters per second (m/s).
  • Height (m): Input the height at which the measurement is taken in meters (m).

Step 2: Calculate

  • Once you’ve input the values for pressure, fluid density, fluid velocity, and height, click the “Calculate” button.

Step 3: View Results

  • The calculator will display the calculated value for the constant ‘c’ based on the Bernoulli Equation (p + 0.5ρv² + ρhg = c).


The Bernoulli Equation is a fundamental principle in fluid dynamics, expressing the conservation of energy for an incompressible, inviscid fluid. The formula is as follows:


  • represents pressure (Pa)
  • stands for fluid density (kg/m³)
  • is the fluid velocity (m/s)
  • denotes the height (m)
  • is a constant along a streamline in the fluid flow

This equation demonstrates the balance between pressure energy, kinetic energy, and gravitational potential energy in a fluid flow system.


Let’s say we have a fluid flowing through a pipeline with the following parameters:

  • Pressure (Pa): 100,000 Pa
  • Fluid Density (kg/m³): 1,000 kg/m³
  • Fluid Velocity (m/s): 10 m/s
  • Height (m): 5 m

By using our Bernoulli Equation Calculator and following the steps mentioned earlier, you can quickly determine the constant ‘c’ for this scenario. Plugging in the values, you will find that . After calculating this, you will obtain the value of ‘c’.
