Ethylene is produced by the dehydrogenation of ethane. If the feed includes 0.5 mol of steam (an inert diluent) per mole of ethane and if the reaction reaches equilibrium at 1100 K and 1 bar, what is the composition of the product gas on a water-free basis?
If one of the machines has its field excitation adjusted such that it delivers 125 A lagging current, determine the armature current, power factor, excitation voltage, and power angle of each machine.
Develop project plans for the design and construction of the following processes. Use Figure 1.2 as a guide to the activities that must occur. Estimate the overall time required from launching the project to the start of operation.

A nuclear power plant generates 750 MW; the reactor temperature is 588.15 K (315°C) and a river with water temperature of 293.15 K (20°C) is available.
Derive the ODE representing this system and solve for the concentration of the outlet stream as a function of time. Plot this until equilibrium is established - derive and solve the equation and plot the new temperature profile.
Determine the pinch temperature and the minimum utility requirements for the process set out below. Take the minimum approach temperature as 15 °C. Devise a heat-exchanger network to achieve maximum energy recovery.
In Figure 9.84, calculate the force that exists between the two faces of the gap. The magnetic path has a permeability equal to μ and the core is d m thick. a, b, and g are the average path lengths of the corresponding magnetic path sections.
Show how each of the following strong electrolytes "breaks up" into its component ions upon dissolving in water by drawing molecular-level pictures. a. NaBr f. FeSO4 b. MgCl2 g. KMnO4 c. Al(NO3)3 h. HClO4 d. (NH4)2SO4 i. NH4C2H3O2 (ammonium acetat..
If the gases leave the tower at 6 atm, 25 °C, and are expanded to, say, 1.5 atm, calculate the turbine exit gas temperatures without preheat, and if the gases are preheated to 400 °C with the reactor off-gas. Also, estimate the power recovered fro..
The R2 for which the developed torque would be a maximum.
Determine the flow rate of the refrigerant, the amount of work in the compressors, and the heat loads in all heat exchangers.
