Original release notes
Pipe Calculator:
- Enhanced Calculations: In the "Calculate Flow from Known Power" section, added the ability to calculate Power (Q) based on flow rate, as well as Inlet/Outlet temperatures (Tin/Tout) based on Q and flow rate.
- High-Precision Mode: Triple-click headers to display additional decimal places for Q, Tin, and Tout.
- Smart Sync: Temperature and flow rate values are now linked between Block 2 and Block 3 (consistent with the Duct module workflow).
- Dynamic Unit Conversion: Improved behavior for alternative units in Blocks 2 and 3. When switching units after entering a value, the app now automatically recalculates the input.
- Bug Fixes:
* Resolved an issue with the glycol concentration dropdown menu.
* Resolved an issue with incorrect viscosity values during SI-to-IP conversion for secondary units.
* Fine-tuned the Friction (pressure drop) conversion factor to 0.122488 for IP systems.
* Adjusted the Glycol Density conversion factor to 0.0625 for IP systems.
Duct Calculator:
- Dynamic Recalculation: Block 3 now automatically updates when humidity values are modified.
- Improved Precision: Enhanced calculation accuracy for Block 3, including Reynolds number (Re) values.
- UI Fluidity: Optimized and accelerated animations for a smoother and more responsive interface.
- UI Improvements: Added grouping frames in the Duct description for better readability.
- Accuracy: Standardized the Friction conversion factor to 0.122488 for IP system consistency.
General Updates:
- Performance: Optimized build size via image compression.
- UX Overhaul: Redesigned the Help menu with categorized sections for easier navigation.
- Input Fixes: Resolved selection glitches in multiple numeric input fields.
- Stability: General performance improvements and minor bug fixes.
