(a) Calculate the length of a T-burner to give a first natural oscillation of 2000 Hz using a propellant that has a combustion temperature of 2410 K, a specific heat ratio of 1.25, a molecular mass of 25 kg/kg-mol, and a burning rate of 10.0 mm/sec at a pressure of 68 atm. The T-burner is connected to a large surge tank and prepressurized with nitrogen gas to 68 atm. The propellant disks are 20 mm thick. Make a sketch to indicate the T-burner dimensions, including the disks.
(b) If the target frequencies are reached when the propellant is 50% burned, what will be the frequency at propellant burnout?
A sinusoidal signal, with amplitude of 3.25 volts, is applied to a uniform quantizer of the mid-tread type whose output takes on the values 0, ±1, ±2, ±3 volts. Sketch the waveform of the resulting quantizer output for one complete cycle of the in..

Calculate the mass flow rate of the propellant, the thrust, and the thruster overall efficiency (including ionizer and accelerator). Assume singly charged ions.
Use equilibrium data from Appendix A.3. Bynumerical or graphical integration, determine NG.Calculate the tower height. (Note: Theequilibrium line is markedly curved, so numerical integration is necessary even for dilutemixture.) (Ans. NG=8.47 tran..
A thermally insulated resistor of 20 ohms has a current of 5 A passed through it for 1 s. It is initially at 20 degrees C.
One compartment is evacuated, the other contains steam at 7.5 bar, 300 °C. The latches are removed and the gas expands to fill the entire volume of the cylinder. When the system reaches equilibrium, its pressure is 1 bar. Determine the final tempe..

If a mixture of steam and ethyl benzene is fed to an adiabatic reactor at 2 bar, 640 °C, estimate the equilibrium conversion and outlet temperature as a function of the ratio of steam to ethyl benzene. What ratio would you recommend using in pract..
Heat conduction in a nuclear fuel rod assembly (Fig. 10B.3) considers a long cylindrical nuclear fuel rod, surrounded by an annular layer of aluminum cladding. Within the fuel rod heat is produced by fission; this heat source depends on position a..
