1. Plot the flame temperature and total entropy (or entropy difference) for burning gaseous hydrogen and gaseous oxygen as a function of the dissociation of water into OH (0-1). Assume that the reactants enter the combustion at 200 K and the products leave at their adiabatic flame temperature. What is the equilibrium dissociation fraction and flame temperature?

2. Repeat the exercise with air instead of pure oxygen
What is the elongation of a rectangular bar (cross section 2 inch * 2 inch length 4 ft) When it is subjected to an axial load of 80,000 lbs. Assume the material of the bar has the following properties G = 7,700 KSI, V =0.30
A simple four-leg intersection needs a 2-phase fixed-time signal. The critical flows in the N-S and E-w directions are 600 and 400 veh/hr, respectively, with a 0.95 peak-hour factor.
a navel gun (E= 30,000 ksi and G = 11,600 ksi) with a bore of 16 in. develops a maximum internal pressure of 20,000 psi. Determine a. the minimum outside diameter required if the maximum tensile stress permitted in the gun barrel is 36,000 psi.
And forms HCN, it will volatilize, and if it volatilizes, HCN can poison mine workers. At pH 10.4, what fraction of the cyanide is in the CN- form?
1. In which circumstance are multiple copies of the same unicast frame likely to be transmitted in a switched LAN. 2.If you want to disable STP on a port connected to a server, which command would you use
A structural element subjected to cyclic loading is made of fc’ = 3000 psi concrete. Compressive stresses are changing between 2200 psi and 1600 psi. The frequency of loading is 8 Hz. After 10 years of uninterrupted loading, evaluate damage of materi..
Water at 68 degrees f is in a long, rigid cylinder of inside diameter 0.600 in. A plunger applies pressure to the water. If, with zero force, the initial length of the water column is 25.00 in, what will it's length be if a force of 420lbs is applied..
A Waste water has been characterized for nitrogen-containing compounds and the TN was 26 mg N/L, the TKN was 14 mg N/L and nitrate was 27.3 mg NO3-/L. What is the potential theoretical oxygen demand (mg O2/L) associated
List all the materials that you see, including different surface treatments and textures - Address all the transparent surfaces that might appear, how will model or show what is beyond those windows?
The plant is to employ alum coagulation. and pertient data for the folcculation basin are as follows: detention time = 20 min, G = 35 /sec at 50F, GT = 10000 to 100000, width = 1.25 depth, length = 2width, no baffling, number of impellers = 2
Suppose the summer daily demand for water use in Phoenix is normally distributed with a mean of 310 million gallons/day and a standard deviation of 45 million gallons/day. Also suppose the city has reservoirs whose combined storage is 350 million ..
