the rated power output of an engine is 7 460W. how much energy would it produce in 10 minutes?
To calculate the energy produced by the engine in 10 minutes, we need to convert the power output from watts to kilowatts and then multiply by the time in hours.
1 kilowatt (kW) is equal to 1000 watts (W), so the power output of the engine is 7,460 W ÷ 1000 = 7.46 kW.
Since we want to find the energy produced in 10 minutes, we need to convert the time into hours. There are 60 minutes in 1 hour, so 10 minutes is equivalent to 10/60 = 1/6 hour.
Now, we can calculate the energy produced:
Energy = Power × Time = 7.46 kW × 1/6 hour = 1.2433 kWh (kilowatt-hours)
Therefore, the engine would produce 1.2433 kilowatt-hours of energy in 10 minutes.
To calculate the energy produced by an engine, we need to use the formula:
Energy = Power x Time
Given that the rated power output of the engine is 7,460W and the time is 10 minutes, we can plug in these values into the formula to find the energy produced:
Energy = 7,460W x 10 minutes
First, we need to convert the time from minutes to seconds because the power is given in Watts:
1 minute = 60 seconds
So, 10 minutes = 10 x 60 = 600 seconds
Now we can calculate the energy:
Energy = 7,460W x 600 seconds
Energy = 4,476,000 joules
Therefore, the engine would produce 4,476,000 joules of energy in 10 minutes.
