3. An industrial plant has an electrical load of 5 MW at 80% lagging power factor. It has been decided to replace a 500 HP induction motor that drives a pump. This motor operates at an efficiency of 90% and a lagging power factor of 90%. If a synchronous motor is purchased as a replacement, which is capable of operating at 0.80 leading power factor, what will be the new power factor of the plant. Assume that both have the same efficiency.
