Simple duct sizing app, both English and Metric units

The S&P duct calculator allows three different calculations tobe carried out quickly and with ease. These calculations aredivided in four areas: 1. Diameter converter, which allowsconverting circular to equivalent rectangular ducts. 2. Calculatorof different ventilation parameters, with which will be able toobtain the diameter, the air speed, the airflow and the dynamicpressure of your installation. 3. Pressure drop calculation toolfor installations with straight sections and duct system elements.4. Units converter, with which you will be able to transform speed,airflow, power and pressure units for other equivalents indifferent scales.

The Quietflex Ductulator app provides calculations for ductinstallation. It allows for project calculation giving the user theability to calculate all runs in a project on one screen. It alsogives volume, velocity, friction loss and duct size calculations.

As easy to use as the paper Duct calculator plus additional offsetcalculations.

a Ductulator - a ductsizingcalculationsprogram for Android OS, is specially designed byaprofessionalengineer to replace the conventionalhand-heldductulator. It is alot more than just a Ductulator.Highlights:- Duct sizing for Rectangular, Round or Oval shape with3+1commonsizing methods (i.e., equal friction, velocity, byductdimensions+ find airflow). Detail results such asvelocitypressure,hydraulic diameter, reynolds number, frictionfactor,relativeroughness and flow area are included.- Rectangular and Oval duct sizes are obtained bydirectiterationalgorithm method, i.e., not converted from roundductsize.- Irregular Shape duct sizing with built-inpolygonshapebuilder.- you're in control; full control and exact oninputparameters,i.e., no sliding bar type of input method which canbedifficult tocontrol to exact input numbers.

Duct Calculator Elite is an industry leadingtool designed to simplify solving everyday problems for HVACprofessionals. This app allows users to calculate the duct size,velocity, pressure drop, and flow rate for ductwork in HVACapplications.Duct Calculator Elite features a highly intuitive interfacewhich allows the user to easily enter values with precision(without the use of cumbersome "slider" controls).In "Duct Size by Airflow" mode, the calculator allows users setairflow and either velocity or friction(Pressure Drop) and thecalculator solves for round and rectangular duct sizes. Aspectratio of the rectangular duct can also be specified.In "Duct Size by Dimension" mode, users can enter either a roundduct diameter or rectangular duct height and width. In addition,users enter either airflow or velocity and the calculator willsolve for the other variables as well as friction.-In "Pressure Drop" mode, users can convert between duct length,pressure drop, and friction values. This allows users to quicklydetermine exact pressure drop of a given installation or calculatethe max duct length that can be used to maintain desired pressuredrop. This feature compliments the two duct sizing calculators.Duct Calculator Elite provides users with a wide variety ofsetting including:-Duct Dimensional Units (Inches, Centimeters, or Millimeters)-Airflow Units (Cubic Feet per Minute, Cubic Feet per Second, CubicMeters per Second, or Liters per Second)-Velocity Units (Feet per Second, Feet per Minute, or Meters perSecond)-Pressure Loss Units (Inches of Water per 100 ft or Pascals perMeter)-Duct Material (Aluminum, Concrete, Fibrous Glass Duct Liner,Flexible Duct-Metallic, Galvanized Steel, PVC Plastic Pipe, SmoothLiner, Spiral Steel, or Uncoated Carbon Steel)-Air Temperature (Fahrenheit, Celsius, or Kelvin)-Elevation (Feet or Meters)The Duct Calculator Elite solver uses friction loss equationscontained in 2009 ASHRAE Handbook - Fundamentals. The next time yougo to a meeting or out to the field, leave your Ductulator at home,you`ll have everything you need right on your iPhone/iPad/iPodTouch!If you are not 100% satisfied with this calculator please emailus at [email protected] we can make things right before posting any negative reviews.
