The indicated mean effective pressure is

Question

In a spark ignition engine working on the ideal Otto cycle, the compression ratio is 5.5. The work output per cycle (i.e., area of the P-V diagram) is equal to 23.625´10⁵´V_C J, where V_C is the clearance volume in m³. The indicated mean effective pressure is
