How do you convert compression ratio and psi?
Compression ratio is a ratio of the volume of gas in an engine's cylinder before and after combustion. To convert compression ratio to psi (pounds per square inch), you would need additional information such as the specific engine's cylinder volume, operating conditions, and fuel type to calculate the pressure generated during combustion. It is not a direct conversion and depends on various factors specific to the engine.
What is the compression psi of 10.1?
251.37
What is the air pressure of an ideal otto cycle which has a compression ratio of 7 and has a 98kpa and 30 degree C at 766kjkg heat transferred during constant volume?
To calculate the air pressure at the end of the compression process in an ideal Otto cycle, you can use the formula for isentropic compression: P2 = P1 * (V1/V2)^gamma, where gamma is the specific heat ratio (1.4 for air). Given the compression ratio is 7, the volume ratio V1/V2 is 7. So, P2 = 98 kPa * (1/7)^1.4 ≈ 26.03 kPa.
What compression ratio does helium need to loose its bouyancy?
Helium loses its buoyancy when it reaches a compression ratio that increases its density to be equal to or greater than the density of air. This usually occurs at a compression ratio of around 1.7 to 2.0 times the original volume.
What is the correct octane rating for 10.5 to 1 compression ratio?
For a compression ratio of 10.5:1, the recommended octane rating is typically around 91-93 octane. Higher compression ratios require higher octane fuel to prevent knocking or pre-ignition in the engine. It is important to use the correct octane rating to ensure optimal performance and to avoid engine damage.
