What is the function of static mixers in selective catalytic reduction (SCR) technique?

Carburizing is the process where: -manganese contributes to the strengthening of the material -the part is quenched in a bath of oil to decrease distorion -carbon is added to the outer layer of a steel part through absorbtion and diffusion. -a part is packed in a salt bath to increase durability

How is the Poisson’s ratio applied?

Pour point depressants keep oil from forming wax particles under temperature operation. Select one: a. Mild b. Warm c. Hot d. Cold

Which of the following characteristics is not describing additive RP methods? Staircase appearance O Shrinkage O Distortion O Limited material choices. O None of above

Calendering is a special manufacturing process in which large volumes of rolled thin plastic films and sheets are produced from a bulk feedstock using a set of consecutive heated rolling steps as shown in the figure below. Based on your understanding of the behavior of polymers, which of the statements below regarding calendering of polymers are accurate? (This question has more than one correct answer) Feedstock Sheetstock

NOTE: If the reaction temperature is too low, little reaction occurs and only a small amount of product is produced (little formation of B) If the reaction temperature is too high, most of primary product B reacts to form a lower-value secondary product (too much of B reacts to form C). So there is a temperature between these limits that maximizes the profitability of this reactor Consider the following data for the cost and values of A, B, and C Cost and value: V=$0.15/mol (cost of A in feed) AF V=$0.10/mol (value of A in product) V=$0.50/mol (value of B in product) V=$0.20/mol (value of C in product) A B Use excel for the following calculation a. Select an arbitrary reactor temperature b. Use mole balance equations obtained in previous slides to calculate for CA, CB, and Cc c. Calculate an objective function (Ø has a unit of $/s) as Product value Feed Cost Ø-EF₂C₁V₁-F₂CAOVAF which is d. Repeat the calculation using a different temperature I would suggest the following format in your…

a) Explain the functions of a plastic coatings. b) Assume you are a Mechanical engineer working in Al Jazeera Steel Company LLC is situated in Sohar. You are assigned a task to setup the system to coat the surface of the hot component dipped in oil. For example the dark blue colour steel gun is shown below. Based on the above scenario, answer the following questicns. i) Suggest the suitable surface coating process. ii) Explain the above surface coating process in detail.

What is in bonded SA fluxes?
