FingerCAD vs Heating Pipe Size

"FingerCAD" is the first CAD application for technical drawing with fingers assisted by computer for portable devices. With "FingerCAD" you can draw houses, bridges, planimetry of apartments, mechanical components, geometrical figures, everything that can be designed with a common PC CAD. Useful for the engineers on construction site, for architects, surveyors, designers, students etc.. The design possibilities with "FingerCAD" are endless and all this using only your portable device, during a travel or comfortably seated or standing at work. The ease of use makes it very useful and versatile. The final design can be saved using standard formats (ex. DXF) and can be sent via e-mail or printed. The zoom and pan, the customization of the drawing, the common cad tools, autosaving and the ability to continue operations even in subsequent sessions of use (at boot "FingerCAD" will load automatically the design saved in the previous session of use), possibility to add measurements and free text makes it truly unique. Each CAD object is treated as a separate object; You can then go back in time by removing the objects from last to first (also in next sessions of work), select and remove the undesired parts / incorrect objects. The "automatic acquisition of nearest vertices" facilitates the drawing of adjacent graphics objects and the function "2x" allows you to draw walls (double line) automatically (you can specify the thickness of the wall as desired). The three RGB components, alpha transparency, the freehand drawing, the ability to fill an object with colors, the color palette, the color picker, in addition to the common functions of a CAD give you the ability to add manual graphical effects at the overall design (also using freehand drawing). MODIFY, COPY AND MOVE for CAD objects (also from one layer to another one). AUTOMATIC CALCULATION OF THE MEASUREMENT OF THE AREA OF A GENERIC POLYGONAL 3D SURFACE. Virtual Reality Exploration: you can walk in the 3D model and observe it using first person view (Finger3D + FingerCAD). HIGH PRECISION OF DRAWING: using the “under finger dynamic drawing preview “ you can see exactly where for example the initial / final point of a line will be placed (observing the preview window that shows the area of drawing not visible under the finger). AUTO-PAN for work area: if you reach the border of the screen, FingerCAD shifts automatically the work area so you can continue to draw longest lines - you have not to use the "zoom out" to draw long lines. .OBJ 2D and 3D export routine: export the CAD design for 3D modeling softwares such as Finger3D, Blender, Maya 3D, etc... or print it using 3D printers DXF export/import for AutoCad, qCad, SolidWorks, LibreCAD, ... PDF export. File formats conversions: - from DXF to OBJ - from DXF to PDF - from DXF to IMAGE (JPG,PNG) 3D models can be displayed directly using the "FingerCAD 3D VIEWER". DROPBOX / iCloud Drive file sharing (IN and OUT) Ability to import DXF files from a WEB LINK and/or from an EMAIL ATTACHMENT. Ability to PRINT the design (using AirPrint). Other features: - CAD (computer assisted design) - Walls with adjustable thickness - Snap to control points - Free text - UNDO/REDO for the graphics objects, from last to first - Selection and ability to transform/move/delete selected objects - Autosave - Grid - Snap to grid - Adjustable grid - Labels indicating the finger position on the cad area - Many selectable unit of measurement - Design multi-layer and multi-floor - The selected objects can be moved or copied from one layer to another layer or from a floor to another floor - Preview of other layers in the current layer - Scale and rotate - Extend - Trim - Mirror - Send with an email the generated .dxf, .obj, .pdf files - Ability to share .dxf, .obj, .pdf with other installed apps - DXF part library (architecture, communication, electrical, electronics, mechanical, misc, processing, templates, zipf_libs)

Estimate required pipe diameter of a closed hydronic heating or cooling system in an instant and calculate pressure drop to determine required circulation pump characteristics (flow and head). Easy to use, quick and accurate results. Enter the required heating or cooling output and water flow and return temperatures. Choose pipe material. The recommended pipe diameter is already there, presented as a standard DN. Additionally, choose the recommended or a custom pipe diameter and specify pipe section length and fittings. Results include water flow rate, velocity, pressure drop and pressure drop per 100 m of straight pipe and can be used to determine the parameters of a circulation pump. ## Features: - Simple to use; - Suitable for hydronic (water-based) heating and cooling systems; - Suitable for a large range of heating and cooling outputs; - Predefined pipe materials; - Water temperature range from 1 to 99 ºC; - Completely independent from any manufacturers; - No login needed, no data connection needed; - No data collection; - No subscriptions, one-time purchase only; - Very quick calculation with no delays; ## Possible uses of the application: - Quickly estimate required pipe diameter when designing a hydronic (water-based) closed heating or cooling system. - Quickly determine circulation pump requirements (flow and head), whether it be a new system or a replacement pump. ## Notes: - It is recommended to calculate every section of the piping system separately and additionally check the whole system pressure drop. - The application is only useful for calculations of hydronic (water based) closed heating or cooling systems. Other systems and media are not supported. - Only metric units are supported. - The application, while accurate, is not meant as a complete replacement of specialized software for heating and cooling system design. The application doesn't require data connection. It doesn't require and doesn't collect any personal data. It also doesn't contain third-party ads or code. Also: no in-app purchases, no subscriptions.
