what is meant by magnetic flow meter ? explain its working
principle ?
Answer Posted / rajesh
it consist of a turbine impeller mounted on a shaft which is
connected to a miniature dc motor . as fluid passes through
turbine , it rotates and velocity of fluid is proportional
to turbine speed . hence if we connect a voltmeter we get
flow reading . it is ideally a active transducer , but since
all fluids have different parameters a small voltage is
applied to turbine , but principle is same

how external lighting design? please give examples?
A 500 V shunt motor runs at its normal speed of 250rpm when the armature current is 200A. The resistance of the armature is 0.12 Ω. Calculate the speed when a resistance is inserted in the field reducing the shunt field to 80% of normal value and the armature current is 100A.
