A 20-hp motor runs 5,000 hours per year, produces 5 hp of shaft work, and operates at 60% efficiency with a power factor of 75%.

Q2. A 20-hp motor runs 5,000 hours per year, produces 5 hp of shaft work, and operates at 60% efficiency with a power factor of 75%.  

A) Calculate the power (kW), energy (kWh) and reactive power (kVAr) produced by the motor.  

B) If motor were replaced with an energy efficient 5-hp motor operating at 90% efficiency with a power factor of 90%, calculate the power (kW), energy (kWh) and reactive power (kVAr) produced by the "right-sized" motor.
