How to Calculate Mean Effective Pressure in Otto Cycle?
Mean Effective Pressure in Otto Cycle calculator uses Mean Effective Pressure of Otto Cycle = Pressure at Start of Isentropic Compression*Compression Ratio*(((Compression Ratio^(Heat Capacity Ratio-1)-1)*(Pressure Ratio-1))/((Compression Ratio-1)*(Heat Capacity Ratio-1))) to calculate the Mean Effective Pressure of Otto Cycle, Mean Effective Pressure in Otto Cycle is a vital parameter that reflects the petrol engine's ability to generate work output. Imagine a constant pressure acting on the engine piston throughout the entire cycle (intake, compression, combustion, exhaust) that would produce the same amount of work output as the actual varying pressure experienced in the real cycle. Mean effective pressure essentially represents that constant pressure. It is calculated based on the engine's geometry (displacement) and the indicator diagram, which depicts the pressure variations within the cylinder throughout the cycle. Mean Effective Pressure of Otto Cycle is denoted by PO symbol.
How to calculate Mean Effective Pressure in Otto Cycle using this online calculator? To use this online calculator for Mean Effective Pressure in Otto Cycle, enter Pressure at Start of Isentropic Compression (P1), Compression Ratio (r), Heat Capacity Ratio (γ) & Pressure Ratio (rp) and hit the calculate button. Here is how the Mean Effective Pressure in Otto Cycle calculation can be explained with given input values -> 1.567738 = 110000*20*(((20^(1.4-1)-1)*(3.34-1))/((20-1)*(1.4-1))).
