An experimental Centrifugal type air Blower suitable for experiments.
It consists of interchangeable impellers of backward, radial and forward
curved vanes, so that the effect of different types of blading could be
well demonstrated.
The approximate discharge of air is 30 cubic meter per minute at a pressure of 25 cm of water column.
Discharge measurement
One Orifice meter and a differential manometer of 1.0 m height to measure the discharge.
Pressure Measurment
Two number of pitot tubes mounted at the inlet duct and outlet duct to
determine the total pressure developed at inlet and outlet of the
blower.
Motor
The Blower is coupled to an induction motor of 3 HP.
The Blower is coupled with a Dynamometer type motor with a stepped
pulley arrangement to run at three different speeds, balance arm, dial
type spring balance with a large size dial etc., to determine the input
power of the blower.
Instrumentaion
Digital temperature indicator to measure suction and delivery side temperature of the blower.
Pressure gauges to measure stage pressure
