To calculate the power of any car, the horsepower parameter is used. Today, it is this value that is indicated in the documents for the car. But still, sometimes the calculation of horsepower is determined in kilowatts per hour. The horsepower of the car can then be calculated again.
It is necessary
- - car;
- - maintenance station.
Instructions
Step 1
When calculating the horsepower of your vehicle, use domestic as well as European measurement systems. In them, one horsepower is 75 kg x m / s. If we decipher this designation, then one horsepower will be equal to the power required to lift a load weighing 75 kg to a height of 1 meter in 1 second. In addition, horsepower can be converted to kilowatts. In this case, one horsepower will be equal to 735.5 W or 0.735 kW. At the same time, the maximum speed that an ordinary horse can develop is called boiler horsepower.
Step 2
To find out the value of the power of the car, it is necessary to translate the indicated numbers in accordance with the above equations. If the power of the car is indicated in kilowatts, then to determine the horsepower, you need the value indicated in the car's passport, simply divide by 0.735. The final figure will denote the amount of horsepower that this car has.
Step 3
For the easiest way to find out the horsepower in a particular vehicle, go to the nearest good service station. Most of these stations have a special installation-computer that can easily determine how many "horses" in your car. Start the car on the platform of such an installation, install it and depress the gas pedal all the way. While your car is running, the computer will perform all the necessary measurements in a few minutes. After that, you can find out the result and estimate how much horsepower your car has. By the way, horsepower was used as a measure of power for the first time in Scotland in 1789. Then a certain James Watt started comparing how many horses are needed to move a steam engine.
