Benzene gas (C6H6) enters a well-insulated reactor operating at steady state at 77oF, 1 atm, and burns completely with dry air entering as a separated stream at 300oF, 1 atm. The combustion products exit the reactor at 1600oF. Kinetic and potential energy effects are negligible. Determine the percent of theoretical dry air provided.

Amodel rocket with a mass of 0.212 kg is launched into the air with an initial speed of 84 m/s. how much kinetic energy will the rocket have at a height of 214 m? assume there is no wind resistance. 634 j 303 j

4. if you were an astronaut on the moon, what would you experience? what would you see from your perspective?

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
