How do you convert compression ratio and psi?
A 1:1 ratio is equal to 0 PSI. 14.7 PSI is equal to a 2:1 ratio. Just multiply your ratio by 14.7 to get PSI, or divide PSI by 14.7 to get ratio. This is only in a perfect cylinder where valves close exactly as the piston reaches the bottom and stays closed the whole way, and if no air bleeds out from the valves, or between the piston and cylinder wall. Not to mention the difference between if it's hot or cold. Plus, according to the math problem, if you had a compression ratio of 1:1, you would be pushing 14.7 psi. So there isn't any REAL way of telling an engines compression ratio without getting the specs for everything.
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 compression of a 12 hp Kohler motor?
The compression ratio of a Kohler 12hp motor varies depending on the specific model and design. It can typically range from 9:1 to 10:1, meaning that the volume in the combustion chamber is compressed to roughly 1/9th to 1/10th of its original volume before ignition. This compression ratio helps improve the engine's efficiency and power output.
What is the compression ratio of 600 PSI?
"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
160 psi equals what compression ratio?
To convert pressure in psi to a compression ratio, you typically need to know the ambient atmospheric pressure, which is approximately 14.7 psi at sea level. The compression ratio can be calculated using the formula: Compression Ratio = (Absolute Pressure inside the cylinder + Atmospheric Pressure) / Atmospheric Pressure. Therefore, 160 psi would yield a compression ratio of approximately 12.9:1 when accounting for atmospheric pressure.
If the psi of a amc 360 engine is 155. What is the compression ratio?
To determine the compression ratio from the psi (pounds per square inch) reading of an engine, you typically need additional information, such as the specifications of the engine, including the displacement and the type of gauge used for the psi measurement. However, a common method is to use the formula: Compression Ratio (CR) = (Absolute Pressure in Cylinder + Atmospheric Pressure) / Atmospheric Pressure. For example, if the atmospheric pressure is approximately 14.7 psi, the absolute pressure would be 155 psi + 14.7 psi = 169.7 psi, leading to a rough compression ratio of about 12.5:1.
What is the pressure of gas in cylinder during combustion?
Depends on the car. If it is naturally aspirated (no turbo or supercharger), then it's easy. Cylinder pressure = 14.5 (1 bar) * Compression Ratio. If however, it's forced induction: Cylinder pressure = ( 14.5 (1 bar) + Boost psi ) * Compression Ratio. For instance, in a naturally aspirated car with a 10.0:1 Compression Ratio : 145 psi = 14.5 * 10 Or in a turbo car with the unreasonably high 10.0 compression ratio with 10 psi boost : 245 psi= ( 14.5 + 10 ) * 10
How do you convert compression ratio and psi?
