Make a simple cross-section sketch approximately to scale of the thrust chamber that was analyzed in Section 8.8. The various dimensions should be close, but need not be accurate. Include or make separate detailed-section sketches of the cooling jacket and the injector. Also compile a table of all the key characteristics, similar to Table 8-1, but include gas generator flows and key materials. Make estimates or assumptions for any key data that is not mentioned in Section 8.8.
Find the rotor copper loss at full load and the speed at maximum torque. Compute the value of the per-phase rotor resistance (referred to the stator) that must be added in series to produce a starting torque equal to the maximum torque.
If 800 GJ per kmol of fuel is transferred as heat to boiler tubes, at what temperature does the flue gas leave the furnace? Assume complete combustion of the fuel.
The motor starting torque.
The standard enthalpy of neutralization of sodium hydroxide solution by hydrochloric acid.
Select a passenger car and calculate the efficiency of the vehicle in converting chemical energy from combustion into kinetic energy.
A 100-kW, 250-V shunt generator has an armature-circuit resistance of 0.05 Ω and a field circuit resistance of 60 Ω. With the generator operating at rated voltage,
Determine the parameters of the equivalent circuit shown in Figure 13.2.5(c).
The dc resistance of the armature at this temperature is 0.0335 Ω per phase. Compute the effective armature ac resistance in per unit and in ohms per phase at 25°C.
What is the final temperature of the calorimeter contents? Explain how this relates to the answer of exercise 88.
How many kilograms of natural gas are flowing through the pipelines per hour ( use different steps required in material balance calculations).
A plant has a batch of 100 kmol of a liquid mixture containing 20 mol% benzene and 80 mol% chlorobenzene. It is desired to rectify this mixture at 1 atm to obtain bottoms containing only 0.1 mol% benzene. The relative volatility may be assumed con..
Estimate the molar ratio of hydrogen to carbon monoxide in the synthesis gas if the feed consists of an equimolar mixture of steam and methane.
