Example
: Velocity measured with an anemometer
v
= 6 m/s, hose
diameter
d
= 63 mm = 0.063 m
The velocity
v
at the end of a flexible hose with an inner diameter of
63 mm and thus the flow rate should meet the specifications given in
NOTICE
The exhaust system must be tested for leakage before you
connect it to the iCAP RQ instrument.
