In power hydraulics, every pressure drop is a loss of your money. Energy that does not reach the receiver is converted into heat. With the tool from BRhydraulic, you can check how many bars you lose during oil transmission.
Pressure Drop Calculator for Hydraulic Hoses (Δp)
Calculate the pressure drop in a straight section of a hydraulic hose.
Engineering Theory – How does our calculator work?
The tool is based on classical fluid mechanics principles. First, the calculator determines the flow velocity and assesses its character using the Reynolds number (Re).
Reynolds number formula:
Re = (v * d * 1000) / nu
Where:
v– flow velocity (m/s)d– internal conduit diameter (mm)nu– kinematic viscosity of oil (cSt)
If the result exceeds 2320, the flow becomes turbulent, generating significantly higher losses. We then apply the Darcy-Weisbach equation to obtain the final pressure drop.
Pressure drop formula:
𝚫p = * (L / D) * (rho * v² / 2)
Where:
– friction coefficientL– conduit length (m)D– internal diameter (m)rho– fluid density (kg/m3)
