Pipe Sizer - Pressure/Gravity 对比 HVAC Spools 的使用情况和统计数据

Pipe sizing app for water systems - both pressure and gravity. Supports S.I and I-P units. The calculations are based on the Hazen-Williams equation for the pressure systems and the Manning's equation for the gravity systems. User can pick from a variety of currently available pipe materials, more will be added in future updates based on users requests. The app automatically recommends the most suitable pipe size for the required flow rate, based on friction rate and velocity limits set by the user. Any feedback is welcome, and will be the basis for subsequent updates.

HVAC Spools

The easy and fast app to record, monitor and calculate and control the weights for HVAC ducts (Type: Rectangular, reducer and Elbow) during Estimation or Construction phase. You are able to add as much as you want buildings or sections, then for each buildings you can add any type of ducts mentioned above. By providing the dimensions, it will calculate the weights with reference to the densities of galvanized sheet, flanges, angles and Stiffeners. automatically will add stiffeners if required in according to the size of ducts. For each section, the total weights, the total length for flanges and stiffeners, angles and the galvanized sheet area will be calculated.
