The property that the vector on the right-hand side of a differential equation points into the interior of the first orthant is obviously a necessary condition for negative cross-effects to be absent. Give a polynomial example showing that it is not sufficient.
The complete combustion of acetylene, C2H2(g), produces 1300. kJ of energy per mole of acetylene consumed. How many grams of acetylene must be burned to produce enough heat to raise the temperature of 1.00 gal of water by 10.0C if the process is ..
Which do you think would make the best resistor and why?
Calculate the diffusion flux at 1027(C (1300 K) for the same concentration gradient and assuming an activation energy for diffusion of 125,000 J/mol.
Natural gas composed of 60. mol% methane, 30. mol% ethane, and 10. mol% propane at 25 °C and 500. psia is fed at a rate of 50. m3/hr into a boiler. In the boiler it is blended with enough air to provide 20% excess oxygen and combusted.
The Brayton cycle has the same 4 processes as the Rankine cycle, but the T-S and P-V diagrams look very different, why is that?
Take the natural gas to be an ideal-gas mixture with temperature-dependent heat capacities for each component given in Perry's Handbook. Is the ideal-gas assumption reasonable?
Find the current I1 through the 20-Ω resistor of the circuit of Figure P2.2.8 by both mesh and nodal analyses.
Design a storage and feed system for the sorbitol powder. Sorbitol has average bulk density 1.48 kg/liter, and can be assumed to have an average particle size of 200 μm.
How much transmit power is required (disregarding power losses at transmitter and receiver ends) for a maximum BER of 10-5, when using:a. Coherently detected BPSKb. By how much must transmit power be increased to maintain the maximum BER of 10-5 if t..
Two coupled synchronous machines are used as a motor-generator set to link a 25-Hz system to a 60-Hz system. Find the three highest speeds at which this linkage would be possible.
Monochlorobenzene is produced by the reaction of benzene with chlorine. A mixture of mono chlorobenzene and dichlorobenzene is produced, with a small amount of trichlorobenzene. Hydrogen chloride is produced as a byproduct. Benzene is fed to the r..
