What is the efficiency of a system if the output power is 9 hp and the input voltage is 240 V and the input current is 30 A? (Use 1 hp = 746 W as your conversion factor. Give answer as a percentage, to two decimal places, and do not enter the percent sign in your answer. Round your answer if necessary.)

A 68.01-hp motor that has an efficiency of 92.62% is soon to be absolete. It will be replaced by a high efficiency motor which is 97.93% efficient. The motor operates 4,485 hours a year. Taking the cost of electricity to be ₱9.05 per kWh, compute for the annual savings due to the installation of the high-efficiency motor instead of the standard motor. Round your answer into two decimal places only.

A family of five is planning to install solar panels on the roof of their home to help reduce the cost of electricity and save energy to help the environment. The family plans to install 10 panels, each with a power rating 600W. On average, a solar panel can produce electricity for 4.5 hours daily. Assume the average cost of electricity is 5.5 cents per kilowatt-hour. How much money will the family save in a year on their electrical energy bill?
A typical discounted price of a AAA battery is $0.75. It is designed to provide 1.5 volts and 1.0 amps for about an hour. Now we multiply volts and amps to obtain power of 1.5 watts from the battery. Thus, it costs $0.75 for 1.5 Watt-hours of energy. How much would it cost to deliver one kilowatt-hour? (Think of a kilowatt-hour of electricity as the power needed to run your dishwasher one time.) How does this compare with the cost of energy from your local electric utility at $0.10 per kilowatt-hour?
You have a Switch LED Lightbulb with the following information: It is equivalent to a 40 Watt incandescent lightbulb. It uses 8 Watts of electricity. It is estimated to last 25,000 hours. The purchase price of the lightbulb is $37.99. The package claims an estimated energy cost of $0.96 per year, but this estimate is not based on local electricity costs. Assume that local electricity costs $0.086 per kW-hr. Based on this information, we can now calculate the cost of ownership for this bulb. The cost of ownership is defined as the purchase price of the lightbulb plus the cost of the electricity required to run the lightbulb until failure. Note the equation below: Purchase price + Total electricity cost = Cost of ownership Calculate the cost of ownership for this lightbulb $37.99 $75.98 $55.19 $40.14
You have a Switch LED Lightbulb with the following information: It is equivalent to a 60 Watt incandescent lightbulb. It uses 12 Watts of electricity. It is estimated to last 25,000 hours. The purchase price of the lightbulb is $42.99. The package claims an estimated energy cost of $1.45 per year, but this estimate is not based on local electricity costs. Assume that local electricity costs $0.086 per kW-hr. Based on this information, we can now calculate the cost of ownership for this bulb. The cost of ownership is defined as the purchase price of the lightbulb plus the cost of the electricity required to run the lightbulb until failure. Note the equation below: Purchase price + Total electricity cost = Cost of ownership Calculate the cost of ownership for this lightbulb.
