Saturated and unsaturated synchronous reactance

The following readings are taken from the results of an open- and a short-circuit test on a 9375-kVA three-phase Y-connected 13,800- V (line-to-line) two-pole 60-Hz turbine generator driven at synchronous speed:

_____________________________________________________________
Field current, A 169 192
Armature current, short-circuit test, A 392 446
Line voltage, open-circuit characteristic,V 13,000 13,800
Line voltage, air-gap line, V 15,400 17,500

The armature resistance is 0.064 Ohms/phase. The armature leakage reactance is 0.10 per unit on the generator rating as a base. Find (a) the unsaturated value of the synchronous reactance in Ohms per phase and per unit, (b) the short-circuit ratio, and (c) the saturated synchronous reactance in per unit and Ohms per phase.
