We know that emf equation of a transformer as as follows. E=4.44fNBA where f=frequency , N=number of turns, B=Flux Density,A=Area, E= Emf in rms Let's consider the turns are put on central limbs of the transformer. Area of the limb = 2.8X3.7 cm squaree. Or A=10.36 cm sq Or A=0.001036meter square. Given E=120V, f=60Hz, B=1.55T. Thus putting this value in the EMF equation of the transformer E=4.44fNBA, we get N= 120/(4.44X60X1.55X0.001036) Or Number of turns N= 280.57. Since we know that Number of Turns should always be integer do Number of Turns N=281. For other part of question , I couldn't find the file .
