Find runtime hours that makes these two motors economically
equal.
2.14 Two electric motors are available to satisfy a continuous demand of 85 kW. Motor 1 has an initial cost of $5,500 with an operating efficiency of 91%. Motor 2 has an initial cost of $4,000 with an operating efficiency of 89%. Each motor has a life of 10 years with no salvage value. The annual cost of electricity to run the machines is $19.20 per kW of demand plus...

Problem 6-30 (algorithmic) Question Help * Two electric motors are being considered to drive a centrifugal pump. Each motor is capable of delivering 100 horsepower (output) to the pumping operation. It is expected that the motors will be in use 2,500 hours per year and the MARR-8% per year. (1 hp 0.746 kW) a. If electricity costs SX per kilowatt-hour, calculate the annual cost of electrical power for each motor b. What cost of electricity (S/kWh) makes the two pumps...

Please show work. Thank you!
Two 180-horsepower (HP) motors are being considered for installation at a municipal sewage-treatment plant. The first costs $6,300 and has an operating efficiency of 77%. The second costs $3,600 and has an efficiency of 70%. Both motors are projected to have zero salvage value after a life of 10 years. If all the annual charges. such as insurance maintenance, etc., amount to a total of 13% of the original cost of each motor, and if...

number 2
PW, AW An electric motor is rated at 10 horsepower (HP) and costs $800. Its full-load efficiency is specified to be 85%. A newly designed, high-efficiency motor of the same size has an efficiency of 90%, but costs $1,200. It is estimated that the motors will operate at a rated 10-HP output for 1,500 hours a year, and the cost of energy will be $0.07 per kilowatt-hour. Each motor is expected to have a 15-year life. At the...
