What is the efficiency of this transformer on full and half load.
1.) A 500kVA transformer has a primary winding resistance of 0.85Ω and a secondary winding resistance of 0.0025Ω. The primary and secondary voltages are 4.5kV and 600V, respectively. The iron loss is 6kW. If the power factor of the load is 0.75, determine the efficiency of the transformer on full load, and on half load.

Last answer:
D Part filled in 5 min = 5(1/12 +1/15) = 5*9/60 = ¾ Part emptied in 1 min when all the pumps are opened, = 1/6 – (1/12 + 1/15) = 1/6 – 3/20 = 1/60 Now 1/60 is part emptied in 1 min Therefore ¾ part will be emptied in 60 * ¾ = 45 mins
