Propylene gas at 400.15 K (127°C) and 38 bar is throttled in a steady-state flow process to 1 bar, where it may be assumed to be an ideal gas. Estimate the final temperature of the propylene and its entropy change.
All that is required is a four-stage counter which, having counted from 0000 to 1001 (i.e., decimal 0 to 9; ten states), resets to 0000 on the next clock pulse. Develop a block diagram of an asynchronous decade counter and show its timing diagram.
Determine the primary to secondary ratio of the line-to-line voltages and the line currents.
A liquid mixture consisting of 100 kmol of 60 mol% benzene, 25 mol% toluene, and 15 mol% o-xylene is flashed at 1 atm and 100°C. (a) Compute the amounts of liquid and vapor products and their composition.
Lowest standard deviation of measurements, As the Quality Control Manager of a chemical company, you are asked to decide between several process methods that are supposed to uniformly mix 37.4 milligrams into a chemical solution.
oleum or fuming sulfuric acid available commercially in concentrations ranging from 20 to 99.9 sulfur trioxide. a.
Using the mole balance equation only, a relationship between conversion in the reactor and the reactor temperature can be obtained. This relationship is shown in the following figure as a plot of XMB versus reactor temperature.
According to the paper entitled "Recursive tracking of vascular networks in angiograms based on the detection-deletion scheme" (IEEE Trans. Med. Imaging 12: 334-341, 1993), what is the purpose of deleting a vessel segment from the image immediatel..
In a process to produce 1000 kgmol/h acetaldehyde, ethane is fed to the reactor at 1500 kgmol/h and the fractional conversion is 0.8. The product stream contains 2 mol% CO2. Calculate the molar composition of the product stream and the fractional sel..
A distillation column separates benzene from toluene using a control scheme similar to that shown in Figure (a). Make a practice HAZOP study of the plant section and add any instrumentation that is needed to develop the full P and I diagram.
What were the materials used in the implant? What were the advantages of the materials used and what was the surface texture of these implants? How did this contribute to the biocompatibility of the implant?
Determine the motor current and speed when the diverter-circuit resistance is made equal to the series-field resistance. Neglect saturation and the voltage drops across the series- field resistance as well as the armature resistance.
At 50 °C, 1.2 bar, the system n-pentane (1), n-hexane (2), and n-heptane (3) exists ion vapor-liquid equilibrium. The mole fractions in the two phases are: x1 = 0.6, x2 = 0.2, x3 = 0.2 in the liquid; and y1 = 0.87, y2 = 0.1, y3 = 0.03 ..
