Assume, you work as the senior engineer for 'Sunshine group of Industries.' One of the units of your industry is connected to a 110 V, 60 Hz electrical power network of Wisconsin Public Service (WPS) in Green Bay. As of today, that unit (R-L type load) consumes 35 kW power at 0.65 p.f. lagging. From the first day of the next month, the unit is going to add a new machine, which includes a large synchronous motor. The rating of that synchronous motor is: 110 V, 10 kW with 0.80 power factor leading.
What will be the new power factor for the unit from the beginning of next month?
