Question: A mine ventilation fan delivers 500 m3/s of sea-level air at 295 rpm and p = 1100 Pa. Is this fan axial, centrifugal, or mixed?

A mine ventilation fan delivers 500 m3/s of sea-level air at 295 rpm and Δp = 1100 Pa. Is this fan axial, centrifugal, or mixed? Estimate its diameter in feet. If the flow rate is increased 50% for the same diameter, by what percent will Δp change?
