An industrial assembly hall is continuously lightedby one hundred 40-W mercury vapor lamps suppliedby a 120-V and 60-Hz source with a power factor of0.65. Due to the low power factor, a 25 percent penaltyis applied at billing. If the average price of 1 kWh is$0.01 and the capacitor’s average price is $50 permillifarad, compute after how many days of operationthe penalty billing covers the price of the power factorcorrection capacitor. (To avoid penalty, the powerfactor must be greater than 0.85.)
