The compression ratio compares the volume of a cylinder at BDC (bottom dead center) to the volume at TDC (top dead center). If the compression ratio is 10.2 : 1 and the volume at BDC is 124 cm3, what is the volume at TDC in cm3 rounded to 1 decimal places?
To find the volume at TDC, we need to divide the volume at BDC by the compression ratio.
Volume at TDC = Volume at BDC / Compression ratio
Volume at TDC = 124 cm3 / 10.2 : 1
Volume at TDC ≈ 12.15686274509804 cm^3
Rounded to 1 decimal place, the volume at TDC is approximately 12.2 cm^3.
To find the volume at TDC, we can use the compression ratio formula:
Compression ratio = Volume at BDC / Volume at TDC
Given that the compression ratio is 10.2 : 1 and the volume at BDC is 124 cm3, we can solve for the volume at TDC.
10.2 : 1 = 124 cm3 / Volume at TDC
To isolate the volume at TDC, we can cross multiply:
10.2 * Volume at TDC = 1 * 124 cm3
10.2 * Volume at TDC = 124 cm3
Dividing both sides of the equation by 10.2, we get:
Volume at TDC = 124 cm3 / 10.2
Volume at TDC ≈ 12.157 cm3 (rounded to 1 decimal place)
To find the volume at TDC (Top Dead Center), we can use the given compression ratio and the volume at BDC (Bottom Dead Center).
The compression ratio is defined as the ratio of the volume at BDC to the volume at TDC. In this case, the compression ratio is given as 10.2 : 1.
To calculate the volume at TDC, we can use the following formula:
Volume at TDC = Volume at BDC / Compression Ratio
Plugging in the values given:
Volume at TDC = 124 cm3 / 10.2
Volume at TDC ≈ 12.15686 cm3
Since the question asks for the volume at TDC rounded to 1 decimal place, the volume at TDC is approximately 12.2 cm3.
