Dilute-phase line sizing from the figures you actually have: the material, the rate, the route. The tool designs the air first and reports every pressure as a central value with its likely range. A conveying test on the actual material is the only way to tighten it.
Sizes a dilute-phase pneumatic conveying system, vacuum or pressure: line bore, air, pressure with its likely range and an equipment list, from your material, rate and route. Quick uses the material database; Advanced takes your own material data and engineering assumptions. It assumes dilute-phase behavior and typical pickup velocities at standard air conditions. Treat the output as budgetary sizing: final line and blower selection depend on the material's actual conveying characteristics.
