Elbow Pressure Loss

This tool allows you to calculate air flow–related pressure losses along HVAC and ventilation ducts, including both friction losses in straight ducts and local losses caused by elbows and fittings. Based on the entered parameters (duct type, cross-section dimensions, airflow rate, air velocity, etc.), the total system pressure loss is determined, providing a critical reference for fan selection, system balancing, and energy efficiency.
