Engineering discipline for mechanical services, a clean interface on iOS.
As a mechanical engineer I combine the experience gained on site with Swift & SwiftUI to build professional tools that speed up engineers' daily workflows, from fire sprinkler design to construction site management. I have designed three iOS applications that bring the NFPA 13, FM Global and BS EN 12845 standards to the mobile platform, all of them on the App Store.

Sprinkler flow: Q = K × √P
Enter the K factor and the head pressure to calculate the flow, or find the pressure required for a target flow. Only the Q = K·√P relationship is applied, no assumption outside the tables is produced. Detailed selection guide: Sprinkler K-Factor Selection.
Flow calculation (Q)
Reverse calculation (P)
The quick pick buttons are K values commonly used in NFPA 13 and EN 12845. For more comprehensive calculations, see the SprinkCalc app.
