Octane, C8H18, a primary constituent of gasoline, burns in air: C8H18(ℓ) + 12 1/2 O2(g) → 8 CO2(g) + 9 H2O(ℓ) A 1.00-g sample of octane is burned in a constant volume calorimeter. The calorimeter is in an insulated container with 1.20 kg of water. The temperature of the water and the bomb rises from 25.00 °C (298.15 K) to 33.21 °C (306.36 K). The heat required to raise the bomb’s temperature (its heat capacity), Cbomb, is 837 J/K. The...

Consider a rocket that burns steadily. The higher pressure in the combustion chamber, the faster the propellant burns. Why is this? The relationship is such that the higher the pressure, the closer the gaseous flame is to the surface and the more effectively it can transfer heat back to the surface thereby gasifying the propellant quicker. The rate of gas generation, ?_? , can be described by the equation: ?_?=?_1 ?^?, where P is the pressure, and C1 and n...

A small gas turbine uses C8H18(l) for fuel and it enters the combustion chamber at 25◦C whereas air coming from the high pressure stage is at 287◦C . The products of combustion leave the combustion chamber at 1167◦C . The fuel is injected at a rate of 0.95 kg/min where it is mixed and burned with 400 % excess air. An analysis of combustions reveals that all the hydrogen in the fuel burns to H2O but only 90% of the...

A rocket motor burns LH2 and LOX. The combustion chamber pressure and temperature are 25 atmospheres and 3517 K, respectively. The area of the nozzle throat is 0.1 m^2. The nozzle exit area is designed so that the exit pressure equals the ambient pressure at 30 km altitude. For the combustion gases, assume gamma is 1.22 and the molecular weight is 16. At an altitude of 30 km, where the local atmospheric pressure is 1186 Pa, calculate (a) the specific...
