Pneumatic Conveyor System: flow and pressure

i have calculated a system using charts, than i have the following data:

Material: Flour. Density 560 kg/m3
System mass flow 1200 kg/h
Equivalent piping length 100m
Pipe diameter 4''
Air transport speed: 1780 m/min - 30 m/s
System head loss: 17 kPa - 1730 mm H2O

compressor data:
Air flow: 15 m3/min
Power 10 hp

is that reasonable?

i need to know if the compressor is the correct for this system

Thank you guys.
