Reconsider Prob. 16-45. Using EES (or other) software, study the effect of the final temperature on the rate of heat supplied for the two cases. Let the final temperature vary from 2500 to 3500 K. For each of the two cases, plot the rate of heat supplied as a function final temperature.
Prob. 16-45
Water vapor (H2O) is heated during a steady-flow process at 1 atm from 298 to 3000 K at a rate of 0.2 kg/min. Determine the rate of heat supply needed during this process, assuming (a) some H2O dissociates into H2, O2, and OH and (b) no dissociation takes place.
(a) how many pounds of ferric chloride per million gallons are used (b) how many pounds of hydrated lime per million gallons are used, assuming a purity of 70 % CaO
A brass alloy has a yield strength of 280 MPa, a tensile strength of 390 MPa, and an elastic modulus of 105 GPa. A cylindrical specimen of this alloy 12.7 mm in diameter and 250 mm long is stressed in tension and found to elongate 7.6 mm

What are Engineering Societies based upon the research? List at least 10 discipline specific engineering societies along with their website addresses.
A 3m deep layer of clay is underlain by impervious rock. An extensive area of fill is to be placed over the site. How long would it take for the clay layer to achieve 90% of its total final settlement.
Can the volume of the solution be more or less than the 5 L? Explain.
What is the reading in the pore pressure transducer immediately before to and immediately after to - How long before 60% of the final settlement will have occurred?
A river 5 m deep flows over a sand deposit. The saturated unit weight of the sand is 18 kN/m^3 and the unit weight of water is 9.8 kN/m^3. At a depth of 5 m below the river bed:
A uniform earth canal in good condition is 17 m wide at the bottom and has side slope of 2 horizontal to 1 vertical. One side slope extends to a height of 7.8 m above the bottom level and the other side extends to an elevation of 1.8 m then extends t..
50 kmol per hour of air is compressed from p1 = 1.2 bar to P2 = 6.0 bar in a steady-flow compressor. Delivered mechanical power is 98.8KW. Temperature and velocities are: T1= 300K T2= 520K u1= 10m s^-1 u2= 3.5m s^-1
When it is dried out in an oven, it weighs 122.7 g. The specific gravity of solids is found to be 2.66. Find the water content, void ratio, porosity, degree of saturation, and wet and dry unit weights.
Discuss whether shoe A (leather) or shoe B (synthetic) is better for the environment based on the data in the table below. Is it possible to weight one aspect (air
