A Diesel cycle with a compression ratio of 20 and a cut-off ratio of 2.5 produces 200 kW of power. Model the Diesel cycle as using an ideal gas with constant specific heats and the heat provided in a constant-pressure closed system process. The air enters the compression stroke at 300 K, and the combustion process begins at the end of the compression stroke. The fuel is decane, and it enters the process at 500 K. (Note: This is not a perfect model for the complicated process in an actual engine.) Consider the overall equivalence ratio of the combustion to be 0.60. The products exit the combustion process at 1300 K. Determine the mass flow rate of decane required to produce the necessary heat for this combustion process.
