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. Distinct input(white)and output(yellow) fields.- different duct materials selection (Galv. steel,Spiral,Aluminium,Carbon steel, PVC, Duct board, Duct liner,Flexible ductandConcrete).- find duct fictional loss rate by Duct Dimensionmethod(usefuldesign tool for existing duct).- find airflow for a given duct sizes (useful designtoolforexisting duct).- built-in Duct Converter, rhoAIR, Louvre Sizer, FanMotorkW,Convert KW-Amp, Duct gauge/weight, Threaded rod hangersizing,txtfile Viewer, Hello! Condensation.- Duct converter module to convert duct sizesbetweenround,rectangular and oval duct.- rhoAIR module to find air density and otherpyschrometricairproperties at state point.- Louvre sizer module to size louvre opening requiredforstructuralopening.- Fan Motor kW module to calculateelectricalpowerconsumption.- Convert KW-Amp module to convert electrical KW - Amp,andcalculateKVA.- Duct gauge/weight module to find duct weight, perimeterandsurfacearea for rectangular, round and oval duct withbuilt-induct gaugeselections (Galvanized steel, Stainless steelandAluminiumduct).- Threaded rod sizer module to size and select threadedhangerrodwith built-in metric-english series of rod sizes,tensilestresscalculator and maximum load calculator.- Hello!
