Sides of the transformer, b) A 220 V dc shunt motor having an armature resistance of 0.25 ohm
carries an armature current of 50 A and runs at 600 rpm. If the flux is
reduced by 10% by field regulator, find the speed assuming load
torque remains the same

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
