Whether you're working on ventilation systems, air conditioning, or fluid flow projects, this app provides a powerful tool right at your fingertips.

🌟 Key Features:

💨 Calculate pressure loss in ducts using the Darcy-Weisbach equation

📏 Support for both circular and rectangular duct shapes

📐 Input parameters include: duct diameter/width & height, duct length, flow velocity, and fluid properties (density, viscosity)

📊 Automatic calculation of Reynolds number and friction factor

🧮 Support for both SI (metric) and Imperial units

🧠 What is the Darcy-Weisbach Equation?

The Darcy-Weisbach equation is a fundamental formula used to calculate pressure loss due to friction in a pipe or duct. It is widely used in fluid mechanics and HVAC applications for accurate analysis and design.

Equation: ΔP = f * (L/D) * (ρ * V² / 2)

Where:

ΔP = pressure loss
f = friction factor (from Moody chart or Colebrook equation)
L = length of duct/pipe
D = hydraulic diameter
ρ = fluid density
V = flow velocity

👷 Suitable For:

HVAC engineers & designers

Mechanical and civil engineers

University students in fluid mechanics

Maintenance & facility technicians

📌 Notes:
This application is for educational and professional use. Always verify results with engineering standards or manuals where necessary.
