For a
centrifugal blower, power consumption is proportional to -
Cubic power of r. p. m.
r. p. m.
Square of r.
p. m.
Square root
of r. p. m.
Cubic power of r. p. m.
For
centrifugal compressor, the relation between power speed (in r.p.m.) and
diameter is given as
For a
centrifugal blower, power consumption is proportional to cubic power of r.p.m.
Hence, the
correct option is (A).
