This core is quite popular in magnetic designs for power electronic circuits. Assume the relative permeability is 1500. All dimensions and turns are provided. To account for fringe effects around the air gaps, consider the effective area to be 5% larger than their physical size. The current in the middle core is 1.0 A. What is the flux in the left, center, and right legs of the core?

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.
