Pipe Calc contains no ads! It is a simple app to calculate rapidly your pipe or duct diameter When you are in a meeting or project discussion you can immediately calculate the size of the needed pipe or duct. This app is simple to use. It does just what it needs to do. There are no unnecessary features, which can confuse you. 1. It calculates the pipe diameter for steam or water pipe, the steam parameters are calculated by the app. The calculated values may be slightly inaccurate however it is negligible for sizing. 2. It calculates the air ducts round or rectangular for a given amount of air with max allowable velocity you can define. 3. For a given heat dissipation it calculates the needed amount of cooling water or cooling air. 4. In the settings you have the choice between different units. You can adjust the stored nominal diameters for each application.
