WebJul 6, 2015 · First, notice that the problem statement does not specify a temperature. The internal energy and enthalpy are given by: U = m c v T. H = m c p T. Therefore: H = c p c v U. For a monatomic gas, such as helium, the ratio c p / c v is very nearly 5 / 3. It follows that: H = 5 3 × 200 = 333.33. Webwhere k is the ratio of heat capacities and has a nominal value of 1.4 at 300K for air. Process 1-2 is the adiabatic compression process. Thus the temperature of the air increases during the compression process, and with a large compression ratio (usually > 16:1) it will reach the ignition temperature of the injected fuel.
