## What is FlowAnalyzer Viewer?

FlowAnalyzer Viewer opens water network models (.inp files) on your iPhone or iPad, runs a hydraulic simulation with the EPANET 2.2 engine, and lets you inspect the results element by element.

WHAT YOU CAN DO
• Open .inp files from Files, Mail, AirDrop or cloud storage
• Run a hydraulic simulation and step through the time periods
• See the network on an interactive map: zoom, pan, touch and hold any node to see its data
• Read pressure, head, demand, flow, velocity and headloss for junctions, pipes, pumps, tanks, reservoirs and valves
• Review hydraulic and time options
• Works offline. Your files stay on your device

EDIT IN FLOWANALYZER
Tap "Edit & simulate in FlowAnalyzer" on the network screen to send the network to FlowAnalyzer (if installed) to edit it. If FlowAnalyzer is not installed, its App Store page opens inside the viewer.
The two apps are separate. They use different EPANET engine versions (2.2 and 2.3.5); results may differ.

FREE
FlowAnalyzer Viewer is free, with no limit on network size. To edit and create networks, there is FlowAnalyzer.

PRIVACY
No account, no ads, no tracking. The app collects no data.

FlowAnalyzer Viewer uses the EPANET 2.2 engine to read and simulate .inp files. It is an independent app, not affiliated with, endorsed by or sponsored by the U.S. Environmental Protection Agency (EPA).
