Calculates pressure drops and flow rates for compressible gas flow in pipes. Offers three modes: calculate inlet pressure, outlet pressure, or flow rate. Supports custom pipe sizes and a database of over 20 gases.
This app calculates gas pressure loss in pipes using various compressible flow equations. It automatically handles gas density changes and provides detailed results including Reynolds number and friction factors. Users can customize pipe materials, fittings, and gases from integrated or custom databases.
This utility estimates natural gas flow rate using standard orifice meter calculations. It's designed for field use by operators, technicians, and engineers, combining meter geometry, flowing conditions, and gas composition for quick, reliable estimates.
