The liquid propellant rocket combination nitrogen tetroxide (N204) and IJDMII (unsymmetrical dimethyl hydrazine) has optimum performance at an oxidizer-to-fuel weight ratio of 2 at a chamber pressure of 67 atm. Assume that the products of combustion of this mixture are N2, C02, H20, CO, H2, O, H, OH, and NO. Set down the equations necessary to calculate the adiabatic combustion temperature and the actual product composition under these conditions. These equations should contain all the numerical... 

Assumptions NoChar A610 cost (2 pallets) 14.44/lb (40 ) is 16.44/pound. Floor-Dry cost 0.15/lb. Diesel fuel weight 7.33 Ib/gal. Disposal cost 1.20/lb.

After establishing the droplet surface temperature at this time, profiles for droplet temperature, gas-phase temperature, fuel weight fraction, and oxygen weight fraction are computed using Equations 15, 22, 23, and 24, respectively.

The importance of the moderator cost to the power cost for a nuclear plant can be seen by the very approximate data indicated in Table VI. In this table, the cost contribution of the moderator material has been calculated for reactor conditions typical of some gas-cooled reactors. The capital cost of the moderator in dollars per installed kilowatt(e) is related to the unit cost of the moderator, the moderator/fuel weight ratio, the reactor specific power, and the plant efficiency by... 

Fuel weight - the total weight of all nuclear fuel loaded in a reactor core. The value should be roughly a product of fuel rod weight, the number of rods per assembly and the total number of fuel assemblies. Data providers should enter the appropriate value in metric tons. 

Average fuel power density - the amount of energy produced by a specific mass of fuel. It can be calculated as a quotient of the thermal reactor power and the total fuel weight. Data providers should enter the actual value in kW/kgU.

Note from equation (3) that as kgff approaches one, M approaches infinity, and i/M approaches zero. If a plot of 1/m versus rod position is made and the curve extrapolated to a i/m value of zero, that control rod position must be such that kg f = 1, and therefore is the critical rod position. Or, if one was working with fuel, it would be the critical mass because the abscissa would then be in grams or some other fuel weight units.
