A Cleaner, More Cost-Effective, Energy Efficient Alternative to Metal Duct work. Use Your Color, Pattern and Even Your Logo. How To Buy DuctSox Products.
This online ductulator calculates the dimensions for both round and rectangular duct options (one dimension should be entered by the user for rectangular duct ). The output also includes air velocity when air static loss is an input (friction method) or it includes air static loss when velocity is an input (velocity method).
Duct type: Metal Ductboard Flex Size by: Friction rate Velocity Friction Rate: per 1ft. Ductulator Calculator Air duct also termed as ductulator is a passage that is used to provide fresh air into rooms, buildings etc. Air ducts may be in circular, square and in rectangular shapes. This online air duct calculator is used to calculate the velocity of air flow feet per minute (FPM), and feet per second (FPS) through any shaped (circle, square or rectangle) ductulator with either diameter, sides or area.
Sheet Metal Duct Friction Loss Calculator. Enter Duct Airflow (CFM), Duct Velocity (FPM), Duct Length and the number of bends. This Ductulator uses the Colebrook equation to calculate the smallest duct size acceptable for the selected friction rate and duct type that stays within the selected ACCA Manual D recommended velocities.
Unless within , the diameter is rounded up to the nearest inch.
HVAC Calculations and Duct Sizing Gary D. Air Ducts Sizing Spreadsheet Template. The velocity method can be done manual or more or less semi automatic with the spreadsheet template below. This template is based on the in the spreadsheet. The Duct Size Calculator is a quick reference tool for approximating duct sizes and equivalent sizes of sheet metal duct vs.
Once you have made all of your selections, with just a couple of clicks, you can generate complete specifications as Word documents in CSI specification format. Online ducting calculator to find the diameter of duct size. Sizing of air duct can be done using Velocity Metho Constant Pressure Loss Method and Static Pressure Recovery Method. duct calculator sizer mcquay online Files at Software Informer.
In this video we explain air duct sizing using equal. Our Blog is Your Source for Design Tools and Expertise to Help You Optimize your HVAC System Design. Office Tools downloads - Duct Calculator by Marinsoft, Inc. Duct sizing calculator free download.
Duct calculator for pc. A compact Metric and Imperial Duct Sizer aka Ductulator. Combines the ease of a visual wheel for rough sizing and a numeral calculator for more precise calculations.
Affords the user the functionality of locking values and synchronizing between the metric and imperial values. Developed by Engineers for Everyone. Use a duct calculator to find the correct duct size.
Use either an online calculator (see Resources) or a manual one that you can purchase from an HVAC distributor. CFM you need a 8-inch diameter duct. DuctSizer - An Electronic duct calculator for sizing duct and. Ductsize - HVAC Duct Sizing and Analysis Duct Sizing - with Full Control. Ductsize lets you create a complete duct system from start to finish, and gives you control over every aspect of the design.
You can let the program size all the ducts for you (using three different sizing methods), or enter your own sizes to analyze an existing design. Used by trainers, educators and technicians to get the following information: - Friction - Velocity - Round Duct Size - Rectangular Duct Size. Align the correct air quantity (CFM) with the friction loss to calculate velocity, round duct diameter and rectangular duct diameter.
Select duct size using friction chart or duct calculator HOW: Using friction chart. For sizing the supply and return trunks select the duct size at the intersecting lines of the friction rate and the equipment CFM. As the trunks are reduced use the total CFM of the remaining downstream branches. Duct Configurator helps you model and size duct supply duct systems.
Fitting Loss Calculator quickly identifies the optimal fittings and sizes for each duct section by comparing their efficiency and cost.
