Write a sample set of performance specifications for a foldable lap tray that will mount on a manual wheelchair. Hints: What should its maximum and minimum dimensions be? How much weight must it bear? Will your add-on lap tray user make the wheelchair user more or less independent? What type of materials should be used?
Cunene is made by alkylation of benzene with propylene over zeolite catalyst. To maximize selectivity to desired products, several beds of catalyst are used inside the same reactor.
In the direct steelmaking reactor based on the reduction of an oxidizing foaming slag by char (carbon) particles and droplets of iron containing 2% carbon. Estimate the total surface area of char and iron droplets needed to achieve the smelting ..
The thermal design of a heat exchanger to recover heat from a kerosene stream by transfer to a crude oil stream was carried out in. Make a preliminary mechanical design for this exchanger. Base your design on the specification obtained from the CA..
If 2.00 MNaOH is available, how would the student prepare the solution? To help insure three significant figures in the NaOH molarity, to how many significant figures should the volumes and mass be determined?
A geometrically similar 200 pump having a similar efficiency curve is used to pump water through 112.5 m of 150 mm pipe, f = 0.025. The static lift is 10 m. Neglecting minor losses in the pipe calculate the flow, head and power required to drive t..
Aniline is manufactured by the hydrogenation of nitrobenzene in a fluidized bed reactor. The reactor operates at 250 °C and 20 bar. The reactor vessel is approximately 3 m diameter and 9 m high. Suggest suitable materials of construction for this ..
Include in your comparison an analysis of the technical issues (e.g., battery capacity, weight, and charging circuitry), cost issues, and . practicality issues (e.g., user preferences, potential for misplacement or improper usage of charger, and u..
What is the concentration of H2SO4 in the following units:
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 select..
Also find the source voltage that would yield I = -8µA.
