Rapid HVAC Duct Sizing 1.22P
Throw away your ductulator and get intothe21st century! Rapid HVAC Duct Sizing takes the trouble outofsizing duct for ventilation, heating and air conditioning. It isaquick, simple, easy to use tool, allowing you to whip outyourphone and give an immediate answer. You don't need to beanengineer to use it - Rapid HVAC Duct Sizing comes withindustrydefault values preloaded so all you need to do is plug inthe airflow and spin the wheel to calculate the duct height. Easy.It is customisable, with both SI (metric) and imperialunitssupported, plus the target velocity and pressure drop are abletobe configured to suit your requirements. The app supports sizingofoval and circular HVAC ductwork, as well as the spaceefficientrectangular duct type most often used in modernconstruction.Sizing of flexible HVAC ductwork is alsopossible..For its engineering calculations, Rapid HVAC Duct Sizing usesahybrid of the equal friction method and constant velocitymethods,selecting for an equal friction but with a set maximumvelocity toavoid acoustic issues. It calculates the friction factorbased onthe preferred methods of Trane, Carrier and ASHRAE - byiterativelysolving the Colebrook equation for the friction factorbased on airflow. Rapid HVAC Duct Sizing then applies this frictionfactor todetermine the pressure drop. Through the use ofhydraulicdiameters, oval and circular duct as well as rectangularductsizing can be done. The velocity is simply calculated based ontheair flow and sizing of the duct. The app compares the velocityandpressure drops calculated to determine the optimal size meetingthefriction pressure drop as well as maximumvelocityrequirements.Despite the robust engineering calculations being performed,thistool is suitable for use by anyone. Mechanical consultingengineersuse it to save time sizing, ventilation, heating andcooling ducts,especially when estimating a new constructionproject. It is greatfor heating and air conditioning installerschecking the sizing oftheir ventilation ducts. Mechanicalcontractors can make changes toduct sizing on site without needingto call in a consultingengineer. Architects find it useful forceiling space sizing,without needing to call in the buildingservices specialists.Builders can use it to scrutinise theirheating and air conditioningcontractors engineering and make surethey aren't taking up morespace in their construction thanrequired. Building owners can checkon the construction work beingperformed to make sure theirventilation, heating and coolingsystems will work properly.This paid version has none of the ads and limitations of thefreeversion, making it faster and more flexible.Get it done right and fast with Rapid HVAC Duct Sizing.Feature Overview:• Sizing of HVAC ductwork using the equal friction (pressuredrop)method and a maximum velocity using engineering calculationsperCarrier, Trane and ASHRAE• Rectangular duct, oval duct or circular duct can be selectedtosuit construction requirements• 3 construction industry standard duct sizing criteria (setsofpressure drop and velocity requirements) included, plus thesecanbe modified to suit the engineering requirements ofyourproject• For oval and circular duct, a fourth engineering criteriaforflexible duct is available, which also changes the roughnessfactorso that friction pressure drop calculations are correct• SI Metric and Imperial units are both included• Quick and simple to use - enter the air flow with the keypadthenspin the wheel to set the duct height. Change between pressuredropand velocity sizing engineering criteria sets with the press ofabutton.• Calculation results have been triple checked against theASHRAEhandbook.
Easy Offset 1.1.2
Easy Offset is an easy to use programdesignedfor Sheet Metal Workers that calculates cut joints,ellcenterlines, and overall lengths for offsets of any angle.Justenter basic dimensions and the app will do the rest.
Savetimeand money:
-faster than using a calculator
-improved accuracy
-no multipliers or trig formulas to remember
-reduces error
-minimize cutting in the field and wasted material
-use any angle
-useful for layout and detailing
-Compound offsets are calculated automatically.
-Arc lengths have been added showing how much to roll fittings foragiven angle.Types of Offsets:
-ells with any radius or angle for round pipe
-ells with radius heel and throat for rectangular duct
-ells with straight heel and throat
for rectangular duct-tap on an angle
for round pipe-rolled ninety
degree ells-wye branches for round pipe and rectangular ductDoing these calculations by hand can be time consuminganddifficult. This app will make it easier.For the HVAC industry.
