Consider an additional pressure drop between the tanks' outlet and the injector (i.e., through piping, valves and cooling jacket) to be 10% of the combustion chamber pressure. Moreover, account for a 10% of "ullage" volume (void space) in both the fuel and oxidizer tanks. In the assessment of the pressurization system use the following considerations: Use the highest pressure drop between the oxidizer and the fuel lines for the design of the pressurization tank Choose among the following pressurizers Pressurizer Nitrogen Helium R [J/kg-K] 296.7 2079 Tstorage [K] 298 298 X [-] 1.40 1.68 Consider an additional pressure drop between the tanks' outlet and the injector (i.e., through piping, valves and cooling jacket) to be 10% of the combustion chamber pressure.
