Task 20346.

Motorcycle engine cylinder has a working volume of 200 cubic centimeters. In operation, the motor in the cylinder occurs adiabatic expansion of the working mixture at an initial pressure P1 = 20 atm. The working mixture comprises a mixture of air and fuel vapor. The compression ratio of the engine, which is the ratio of the maximum volume of the working mixture to its minimum volume, is alpha = 6. What is the power developed by the engine at a speed of n = 3000 rev / min? Working mixture considered ideal diatomic gas.
