Ammonia gas enters the reactor of a nitric acid plant mixed with 30% more dry air than is required for the complete conversion of the ammonia to nitric oxide and water vapor. If the gases enter the reactor at 348.15 K (75"C), if conversion is 80%, if no side reactions occur, and if the reactor operates adiabatically, what is the temperature of the gases leaving the reactor? Assume ideal gases.
Determine the membrane area needed. Given: Membrane properties and mass transfer information - Develop a process schematic
The per-phase equivalent circuit shown in Figure 13.2.6 of a three-phase, 600-V, 60-Hz, four pole, wye-connected, wound-rotor induction motor has the following parameters: R1 = 0.75 Ω, R'2 = 0.80 Ω, Xl1 = X' l2 = 2.0 Ω, and Xm = 50 Ω. Neglect the ..
It is proposed to use an existing distillation column, which is fitted with a dephlegmator (reflux condenser) that has 200 vertical, 50 mm i.d. tubes, for separating benzene from a mixture of chlorobenzenes.
The core loss at rated voltage is 45 W, and the copper loss at rated load is 100 W. Neglect the exciting current of the transformer. Find the per-unit voltage regulation when the transformer is supplying full load at 110 V and 0.9 lagging power fa..
List in detail all information and data necessary to determine if a proposed tube diameter and gauge number would be satisfactory.
Five different batches of a commercial plastic are sampled to determine the variation of inert additives between batches. Since each batch consists of several thousand pounds of material, several samples are taken from each batch to determine the ..
The final temperature of the uranium and deuterium oxide mixture is 28.5C. Given the densities of uranium (19.05 g/cm3) and deuterium oxide (1.11 g/mL), what is the edge length of the cube of uranium?
What are the units commonly used in occupational exposure limits for quantifying the concentration of dust particles, vapours or gases and fibres? What does LD 50 mean in Industrial Toxicology
Water at 1 bar, 20 °C is heated at const P to produce steam with quality 95%. What is the amount of heat? What is the final state if the amount of heat is 2100 kJ/kg?
Discuss how the phase equilibria of mixtures are represented using diagrams similar to the pressure-temperature and pressure-specific volume diagrams for one- component systems. Use the example of a mixture of ethane and heptane to illustrate your..
Wet steam at 200 °C with 80% moisture is heated by removing 600 kJ/kg of heat. Determine the final state (pressure and temperature and quality, if a two-phase system) if cooling is at constant pressure.
