15. A factory takes a load of 2,400 kva at 0.6 lagging power factor. A synchronous motor having an input rating of 1,500 kva is to be installed to carry an additional load of 1,200 kw (output) and also to improve the power factor. Assuming a motor efficiency of 92.4 per cent, calculate: (a) the over-all kilovolt-ampere load; (b) the over-all power factor; (c) the synchronous motor power factor.
