In solid state sintering, will atoms diffusing from the particle surface to the neck region by lattice diffusion have slower sintering rate than atoms diffusing from the particle surface to the neck region by surface diffusion?

An old storage tank of “46” m3 stores steam at 6000 kPa and 330 °C. A crack develops at the
top wall of the tank and steam starts to leak out to the atmosphere. An engineer realizes the
problem on time and stops the leak when the pressure inside the tank is below 4000 kPa. If
the leak is assumed to be adiabatic and reversible,
a) What is the final temperature of the steam remained in the tank? (10 points)
b) How much steam is released to the atmosphere? (10 points)

A steam power plant operates on a practical Rankine Cycle. The steam enters the turbine at 3 MPa and “648” K and is condensed in the condenser at a pressure of 46 kPa. You are assigned on a project to improve the thermal efficiency of this plant. a) Draw the schematic of the plant and determine the thermal efficiency of the practical cycle assuming that the efficiencies of pump and turbine are 0.75 and 0.7, respectively. ( b) Draw a TS diagram and show your suggestions for improving the thermal efficiency (i.e. increasing/decreasing temperature of steam entering into turbine, increasing/decreasing pressure of the boiler or condenser, and any other option). Show the effect of each case you suggest on a TS diagram. Discuss also the quality of steam in each case.

Your boss has told you that you need to process a full 55 gallon drum of 1-butene that is stored at 15 atm and ambient temperature. You are going to combust this material with the stoichiometric amount of air at 1 atm and the product gasses will emerge at 579 oF with a conversion of 97%. You have a metal gas sphere that is 55 feet in diameter at ambient temperature that contains the air you are feeding in. You want to make sure you have enough air on hand. The 1-butene enters through a pipe that is ½ inch in diameter, while the air comes in through a 1 ½ in diameter pipe. The flue gases exit through a stack that is 6 inches in diameter. If you use another resource for physical properties, remember to cite it. Answer the following questions:

1) What does the pressure gauge on the tank need to read in order for you to make sure you have enough air, in psig?

Consider a solid spherical medium B with area P and density ρ. The sphere is subjected on both sides to different concentrations C, of species A to which it is permeable. The boundary surfaces at inner radius r1 to outer radius r2 are located within the solid adjacent to the interfaces, and the mole fractions of A at those surfaces are maintained at and respectively at all times. If DAB is the binary diffusivity of A through B, show through the basis that the molar fraction of species A through the sphere at can be expressed as; Ndiff,A, Sphere=4pier1r2CDab(Ya,1-Ya,2/r2-r1) and in terms of the concentration of A at the interfaces as: Ndiff,A,sphere=4pier1r2CDab(Ca,1-Ca,2/r2-r1) (b) Given inner and outer diameter of surfaces of B to be 4.68m and 4.80m respectively; moles per volume of A at the inner surface of B is 0.087 kmol/m3 and the same is negligible at the outer surface. Assuming there is no diffusion in medium B and the total molar concentration is constant, determine the mass flow rate of A by diffusion through medium B.
