A reciprocating engine for light aircraft, modeled after the Avco Lycoming 0.235 engine, has the following characteristics: bore = 11.1cm, stroke = 9.84 cm, num- ber of pistons = 4, compression ratio = 6.75, mechanical efficiency = 0.83. It is connected to a propeller with an efficiency of 0.85. If the fuel-to-air ratio is 0.06 and the pressure and temperature in the intake manifold are 1 atm and 285 k, respectively, calculate the power available from the engine - propeller combination at 2800 rpm.
