What is the ratio of the burning area to the nozzle throat area for a solid propellant motor with these characteristics? Also, calculate the temperature coefficient
(a) and the temperature sensitivity of pressure (πK).
Nitrobenzene is fed to the reactor as a vapor, with three times the stoichiometric quantity of hydrogen. The conversion of the nitrobenzene, to all products, is 96%, and the selectivity for aniline is 95%.
Nitrogen is compressed adiabatically in a closed system from initial pressure P1 = 1 bar, T1 = 5 °C to P2 = 5 bar. Due to irreversibilities there is an entropy generation equal to 4.5 J/mol K. Calculate the temperature at the end of the comp..
Problem 3.30: 1 mol of liquid hexane at 10 bar, 25 °C, is mixed adiabatically and under constant pressure with hexane vapor at 180 °C.
Draw a PV graph and show this process. Show all the relevant temperatures and pressures as well as the critical isotherm and the critical pressure.
Consider the operation of a dc shunt motor that is affected by the following changes in its operating conditions. Explain the corresponding approximate changes in the armature current and speed of the machine for each change in operating condition..
If a saturated solution of NaHCO3 at 60°C is cooled and comes to equilibrium at 30°C, what percentage of the dissolved salt crystallizes?
Discuss the method and comment on its extension to more complex finite elements.
