A turbine flowmeter has a bore of internal diameter 150 mm. The
rotor consists of eight
blades, each of mean thickness 5 mm, mounted on a hub of mean
diameter 35 mm. The clearance
between each blade tip and the bore is 1 mm, and the inlet blade
angle at tip is 20°. Estimate
the meter factor K in pulses/m3.
