A system has been devised to store acetonitrile safely at high pressures and temperatures. The acetonitrile is contained in a 0.2-ft3 tank maintained at 4500psia and 550°F. This tank is placed inside a second tank whose volume, excluding the volume of the first tank, is 2 ft3. Nitrogen at 10.0 atm and 550°F is contained in the second tank. Use the compressibility chart to estimate the final system pressure (atm) if the first tank ruptures and the final system temperature is 550°F. The critical temperature and pressure of acetonitrile are 548 K and 47.7 atm, respectively.
For the following reactions:a. Specify which of the following equations represent oxidation-reduction reactions. b. Write the balanced half-reactions for the reactions you identified as redox in part a. c. Identify the species being oxidized and th..
A jacketed vessel is to be used as a reactor. the vessel has an internal diameter of 2m & it fitted with a jacket over a straight section 1.5m long. both the vessel & jacket walls are 25mm thick.
At a power angle of 30°, the power developed by the motor is 33 kW. Determine the reactive kVA of the motor, and the overall power factor of the motor and the load.
Which proteins are included in the models? What role does phosphorylation play in the models? How do the proteins regulate the cell cycle?
How many planes would it take to consume the entire annualworld production of 4.02 X 109 metric tons of crude oil?
A four-pole, lap-wound armature has 144 slots with two coil sides per slot, each coil having two turns. If the flux per pole is 20 mWb and the armature rotates at 720 r/min, calculate the induced voltage, given that the number of parallel paths is..
Discuss the consequent effects on the real and reactive power losses, and on the voltage drop across the series impedance of the transmission system.
Neglect rotational and stray-load losses. If the rotor-circuit resistance in all phases is increased to 5 times the original resistance,
Determine the energy and entropy balances and compare the efficiency of this process to the simple vapor-compression cycle without recirculation.
Negligible heat is transferred from the nozzle to its surroundings. The approach velocity of the steam is negligible. The specific enthalpy of steam is 2974J/kg at 260°C and 7bar and 2860kJ/kg at 200°C and 4bar. Use the open-system energy balance ..
Let the property P;.. in Eq 5.2-1 be the scalar 1 so that the integral in that equation represents the instantaneous volume V. Show that in this case
