DPregunta 1 5 ptos A standard electric motor is rated at 10 horsepower (HP) and costs $800. Its ful-load efficiency is specified to be 87%. A newly designed, high efficiencymotor of the same size has an efficiency of 93%, but costs $1,200. It is estimated that the motors will operate at a rated 10-HP output for 2.500 hours a year, and the cost of energy will be $0.07 per kilowatt-hour. Each motor is expected to have 12-year life. At the end of 12 years, the first motor will have a salvage value of $50, and the second motor will have a salvage value of $100. Consider the MARR to be 8%. (Note: IHP-0.7457 KW) Un motor elctrico estndar de 10 hp cuesta $800. Su eficiencia de carga est especificada en 87%. Un motor de eficiencia alta de 10 hp tiene una eficiencia de 93% pero cuesta $1,200. Se estima que los motores operarn por 2,500 horas por ao y que el costo de energa ser $0.07 por kilowatt-hora. Cada motor durar 12 aos. Al final de 12 aos el primer motor tendr un valor residual de $50 y el segundo motor tendr un valor residual de $100. Considere un MARR de 8% (Nota: 1 hp 0.7457 Kw) What is the annual energy cost for the standard electric motor (understand the following answers as negative values)? Cul es el costo anual de energa para el motor estndar elctrico (entienda las siguientes contestaciones como valores negativos)? o $1.403 O $1.500 $1.106 o $1,132
