How can we calculate the electrical energy consumed by an electric vehicle with a 40-horsepower motor running continuously for 3 hours at maximum output?
The electrical energy consumed by an electric vehicle with a 40-horsepower motor running continuously for 3 hours at maximum output is approximately 89.484 kilowatt-hours.
Calculating Electrical Energy Consumption
Electric vehicles are becoming increasingly popular due to their eco-friendly nature and cost efficiency. One important aspect to consider when using an electric vehicle is the amount of electrical energy consumed during operation. To calculate the electrical energy consumed by an electric vehicle with a 40-horsepower motor running continuously for 3 hours at maximum output, we need to follow these steps:
1. Convert Horsepower to Watts: Since power is measured in watts, we first need to convert the motor's horsepower rating to watts. 1 horsepower is equivalent to approximately 745.7 watts. Therefore, a 40-horsepower motor is equal to 29828 watts or 29.828 kilowatts (kW).
2. Calculate Electrical Energy Consumed: The electrical energy consumed is measured in kilowatt-hours (kWh). To find this value, we need to multiply the power in kilowatts by the running time in hours. Therefore, the calculation is: 29.828 kW * 3 hours = 89.484 kWh.
Therefore, the electrical energy consumed by an electric vehicle with a 40-horsepower motor running continuously for 3 hours at maximum output is approximately 89.484 kilowatt-hours.
