Benzene at 80 C is burned with 30% excess air at 100 C. Conversion is 90% with 85% going to CO2. The flame temperature is 670 C, calculate the Q.

Spherical napthalene ball of mass 4 gm is kept suspended in a large
volume of stagnant air at 318 K and 1 atm pressure. If the naphthalene ball gets
sublimated directly into the dry air, calculate the time required for the reduction in
the mass of ball from 4 gm to 3 gm. Derive the expression for calculation of time
required. Data: DAB = 6.92 × 10-6 m2/s, sublimation pressure of naphthalene at 318 K is 0.8654 mm Hg and density is 1140 kg/m3.

Knowing that at 0 ^oC and an oxygen pressure of 1.00 atm, the aqueous solubility of O₂ (g) is 48.9 mL O2 per liter. The approximate values for the molarity of O₂ (g) in solution and the partial pressure of O₂ above a 8.23 x 10^-4 M O2 (g) saturated aqueous solution at 0 ^oC are respectively:

A. 2.18 M and 3.78 x 10^-4 atm

B. 2.18 x 10^-3 M and 0.378 atm

C. 0.0446 M and 0.0179 atm

D. 44.6 M and 1.84 x 10^-5 atm

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.

There are 2 geologic provinces represented on the map: one generally to the Northeast Appalachians) or the other in the Southwest (Coastal plains) 1. What is range of the ages of rocks in the northeast province (Appalachians); these rocks were the product of what type of plate boundary? a. Convergent b. Divergent c. Transform d. None - Passive Margin 3. What is the range of ages of rocks in the southwest province (Coastal Plain)? 4. These rocks were the product of what type of plate boundary? a. Convergent b. Divergent c. Transform d. None - Passive Margin 5. What type of structure exists in central Tennessee near Nashville? 6. Describe the nature of the contact between the folded Appalachians and the relatively flat overlying coastal plain?

How did life for African American emigrants to Canada compare to the US?

Mongolia, latitude and longitude I need to know everything about it.  Physical Characteristics Human Characteristics, Human/Environmental Interactions,

Movement with how much ease and ability do ideas, goods, and people flow in and out of the region or subregion you have selected? What drives this movement?

Ethylene is produced by the dehydrogenation of ethane and the following reactions took place

C2H6 -> C2H4 + H2

C2H6 + H2 -> 2CH4

Using molecular balance. Calculate % Yield of C2H4, if the % conversion of C2H6 is 80 % and the selectivity, mole C2H4 per mole CH4, is 1.75. Calculate also the % composition by mole of the product gases.
