Question:

In an engine a mixture of liquid octane and ethanol, mole ratio 9;1, and stoichiometric air are taken in at T0, P0. In the engine the enthalpy of combustion is used so that 30% goes out as work, 30% goes out as heat loss and the rest goes out the exhaust. Find the work and heat transfer per kilogram of fuel mixture and also the exhaust temperature.
