A convenient tool to help you calculate the static pressure in your ventilation system, determine the appropriate airflow and ensure proper fan selection.

Use our Static Pressure Calculator for estimating static pressure in your air ventilation system. There is also a “hydrostatic pressure”, a pressure exerted by a fluid column at rest in pipe systems. To better understand your HVAC fluid dynamics and learn about the hydrostatic pressure formula, see the Hydrostatic Pressure Calculator section below.

Nov 12, 2024 · The CFM to Static Pressure calculator is a tool used to estimate the static pressure (SP) in an HVAC system or ventilation ductwork based on the airflow rate (CFM). Static pressure is an important parameter in air-moving systems as it helps determine how much resistance the air will encounter as it moves through ducts, filters, and other ...

Head loss or major loss in air ducts - equations and online calculator for rectangular and circular ducts - Imperial and SI units.

Oct 3, 2024 · Calculating static pressure from CFM (Cubic Feet per Minute) is an essential aspect of HVAC (Heating, Ventilation, and Air Conditioning) system design and analysis. It allows engineers and technicians to understand the resistance air faces as it moves through a duct system, which is crucial for ensuring efficient airflow and system performance.

Free online ductulator for sizing of HVAC ducts.

External Static Pressure (ESP) is a primary data point when selecting a fan for HVAC applications. It is the measurement of all the resistance in the duct system that the fan must work against. The ESP calculator can be used to estimate static pressure losses for your fan and the associated ductwork.

Aug 8, 2024 · To calculate the static pressure in a duct, add the pressure loss due to straight ducts, duct fittings such as elbow, reducer and tee, and the pressure loss due to equipment including dampers and grilles. Select a fan that has an external static pressure greater than the static pressure in the duct.

Convert airflow rate (CFM) to static pressure using the CFM to Static Pressure Calculator, facilitating HVAC system design and analysis.
