Oranges contain about 15 wt.% solids and 85 wt.% water. In a plant, manufacturing lines A and B are used for the production of orange jam. In the manufacturing line A, crushed orange and sugar are mixed in a 45:55 mass ratio, and the mixture is heated to evaporate water until the residue contains one-third water by mass. (Both line A and B are single units material balances)

(a) Draw and label a flowchart of this process for line A separately.                                                 (5)

(b) Calculate how many pounds of oranges are needed to make a pound of jam.                          (5)

(c) Making a pound of jam is something you could accomplish in your own kitchen (or maybe even a dorm room). However, a typical manufacturing line for jam might produce 1500 lb_m/h. List technical and economic factors you would have to take into account as you scaled up this process from your kitchen to a commercial operation.                                                                                                                  (6)

(d) In the manufacturing line B, the velocity of the orange jam stream containing about 15 wt% solids and 85 wt% water was measured to be 10.5 m/s and the radius of the piping was 8 inches. Line B has the same mixing mass ratio as line A.

e) Calculate the mass flow rate of the orange jam product.                                                              (10)

f) Calculate the number of oranges per year that can be processed with this process if it is run 8 hours a day and 360 days a year. Ignore changes due to unsteady state at startup. Use the following data: Mass of an orange: 0.4 kg Water content of an orange: 85% Density of the solids: Since its mostly sugars, it’s about the density of glucose, which is 1.540g/cm³                                         (6)

a. 500 mol/h methane at 40°C was fed to a furnace and burned with 15% of excess air at
80°C. The exit gas products comprise of CO2 and CO in mol ratio of 15 (CO2/CO), where
all methane was burned during the combustion. The product gas leaves the furnace at
380°C. Determine the amount of heat loss from the furnace in kW.

b. During the combustion process in part (a), the heat produced is used to heat up the water
to produce steam. By considering the changes of the following conditions for the same
process in part (a), predict the changes to the production rate of steam and justify your
answer:

energy balance

List the two wavelengths of light that are NOT absorbed by the Earth’s atmosphere. Of the two name which is impervious to the atmosphere so there is no reason to observe above it. Concerning the other one, why is it still useful to place the telescope above the atmosphere if this wavelength is not absorbed?

1. Hence, if this supply of heat is cut down, obviously, there will be no source to make the water boiling and in that case, geyser will stop working or erupting. There are chambers of boiling water underground and if this supply is cut, eruption will stop.

Question 1 0 / 1 pts Which statement below best defines social darwinism? It based on the idea that there are groups in society that are more evolved than other. The British and the United States used it in order to justify the conquering and subjugation of people all over the world. It is Darwin's theory of evolution where it explains that certain species die off while others survive overtime. It is the theory that says that we are the creation of God(s) and that we are made in his image to this day. It is a theory that expands on Charles Darwin's theory by adding the important of social factors to the evolution of the species in the natural world. It is a theory that proposes the elimiation of certain populations in order to ensure the reproduction of the white race.

111 m³/min of hydrogen measured at normal conditions and nitrogen at a 300% excess enter an isobaric reactor. The inlet gases at 490°C are reacted in the presence of a catalyst to synthesize ammonia. The process has an efficiency of 33%. The exhaust gases are cooled to -40°C to condense the ammonia. Assume that the Cp of the gas phase species can be used in the temperature range, and that Cp NH3 (l) = 0.071938 kJ/mol K. Calculate the overall heat flow of the system in kW.
