Description:Compressible Gas Flow Calc is a professional engineering calculator for fast, reliable compressible flow analysis. Ideal for students and engineers in aerospace, energy, chemical, and HVAC, it streamlines nozzle and orifice sizing, choked-flow checks, and pipeline pressure drop evaluations. One-tap solvers, clear inputs, and instant results help you move from concept to decision faster.
Core features include ready-to-use models for isentropic, choked, Fanno, and Rayleigh flow, plus nozzle and orifice mass flow and critical pressure ratio checks. Smart unit handling (SI and US), built-in gas properties, and configurable assumptions reduce setup time. Generate polished reports, export CSV, and run what-if scenarios to compare designs side by side. Perfect for classroom learning, quick feasibility checks, and high-efficiency engineering workflows.
How to use:1. Download and install, then open the app and select your preferred units (SI or US). You can create a profile to save settings or continue as a guest.
2. Choose a calculator such as Isentropic Flow, Choked Flow, Nozzle Sizing, or Pipe Pressure Drop.
3. Enter known inputs like upstream pressure, temperature, gas type, and geometry. The app auto-handles units and highlights required fields.
4. Tap Calculate to see key results including Mach number, mass flow rate, pressure ratios, and choked-flow warnings. Adjust inputs to compare scenarios.
5. Save or export results to PDF or CSV, and use Advanced options to set gas properties, compressibility factor, safety margins, and default assumptions for future projects.
