What is surging in centrifugal compressor. how its happened

Answer Posted / mohmmmed
Surging is a momentary back flow through the compressor from
the discharge to the suction.This can occur when the mass
flow of gas to the compressor falls below a critical level
with a high pressure difference across the m/c.when there is
not enough gas to replace that being pushed

Assume a DC motor with the following parameters : Motor torque control = 0.0848 Nm/amperes Back EMF control = 0.0848 Volts/(rad/s) Armature resistance = 0.75 Moment of inertia = 0.00001696 kg/m2 With zero frictional load and taking a feed forward gain of 2, determine the motor response for a unit step function. please forwaded the answer to the below mail id thanks in advance Regrads, peer_kaba@yahoo.co.in
