# Differential Pressure Calculator English Español

The difference of pressure between the two points in a system is known as Differential pressure. This measurement is useful in weather instrumentation, airplanes and cars to identify the functionality of pressure. It is commonly used in domestic and industrial applications as it forms the basis of other measurements such as density, viscosity, etc. Use our online Differential Pressure Calculator to find the Differential pressure Flow Rate Measurement/Calculation.

Code to add this calci to your website  #### Formula:

Differential Pressure = (1.59923 x P x d4 x ρ) / W2 Where, P = Change in Pressure d = Pipe Diameter ρ = Fluid Density W = Mass Flow Rate

### Example:

Calculate the flow rate pressure difference having fluid density as 5 kg/m3, diameter of pipe as 7 mm, flow rate of mass as 12 kg/hr and pressure change as 15 bars.

#### Solution:

Differential Pressure = (1.59923 x P x d4 x ρ) / W2
= (1.59923 x 15 x 74 x 5) / 122
= 1999.8704
