For a 3-phase, 600 V, 60 Hz, Y-connected, 6-pole
induction motor at rated conditions the slip is
equal to 0.02. For this motor given that (in
Ohms): R = 0.15; R =0.2; X = 0.4; X=0.5;
X-25
The speed of the rotor field relative to the stator
rotating field is:

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
