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.
One of the classical methods for the determination of the manganese content in steel is to convert all the manganese to the deeply colored permanganate ion and then to measure the absorption of light.
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
If expansion in the nozzle is isentropic and if the nozzle exhausts at 1 bar, what is the pressure at the nozzle inlet (turbine exhaust) and what is the velocity of the air leaving the nozzle?
Estimate a value for the total project cost that will give 98% confidence that the project can be carried out within the amount estimated.
The nutritional information on a cereal box shows that one serving of dry cereal has 90 calories (actually kilocalories). If one were to burn a serving of cereal, the amount of heat given off would be sufficient to raise the temperature of 1 kg of..
Calculate the work done in the isothermal reversible expansion of one mole of CH4 (g) from 1.00 dm3 to 10.00 dm3 at 300 K. Treat methane as a van der Waals gas. The van der Waals gas constants for methane are: a=2.3026 dm6⋅bar⋅mol-2 and b=0.043067 dm..
The speed of the rotor rotating magnetic field with respect to the stator rotating magnetic field in r/min.
Calculate the induced armature voltage at rated load and terminal voltage. Take 2 V as the total brush-contact drop.
What is the average billing to collection time (cycle time)? (Hint: instead of using # of entities, think about the Little's law with # of dollars going through the system.)
Determine the minimum electric potential difference (in volts) that must be applied to accelerate an a-particle so that on interaction with a hydrogen atom, a ground state electron will be excited to n = 6
What are the major drivers and forces of Australia's economy, such as major cities, major products and manufacturing locations, where raw materials come from, and transportation networks that have either created corridors or barriers to economic d..
100 m3/min of a gas mixture containing 1 mol % water and 99 mol % air is cooled at constant pressure of 1 bar from 200 °C to 25 °C. 50 % of the water in the inlet stream is condensed during this process.
