A chemical plant with a fixed capital investment of $100 million generates an annual gross profit of $50 million. Calculate the depreciation charge, taxes paid, and after-tax cash flows for the first ten years of plant operation using straight-line depreciation over ten years and using MACRS depreciation with a five year recovery period. Assume the plant is built at time zero and begins operation at full rate in year 1. Assume the rate of corporate income tax is 35% and taxes must be paid based on the previous year's income.
The liquid stream from the scrubber goes to a dryer where the water is driven off leaving pure maleic anhydride - The moles of benzene that are completely oxidized in the reactor per mole of benzene fed into the reactor?
between the analyses obtained during the two shifts?
What is the volumetric efficiency
At full load and rated voltage, the line current is 40 A, and the flux is 5% less than its no-load value because of armature reaction. Compute the full-load speed.
Calculate the material and energy balances and perform an entropy analysis of the mixing point, the heat exchanger, and of the entire process. The heat capacities of methane and carbon monoxide are CPA = 40.8 J/mol K, and CPB = 29.4 J/mol K, r..
(1) Determine the mass and the temperature of the steam in an insulated piston-cylinder arrangement if sufficient steam is admitted to displace the piston by one cubic foot. The cylinder originally is empty, and the piston main- tains a constant pres..
n-Octane is compressed reversibly at constant temperature along the critical isotherm until the critical point is reached. The initial pressure is 1 bar. The pressure takes place in a closed system. Use the Lee-Kesler method to calculate what is t..
The half-life of a radioactive sample is 30 min. If you start with a sample containing 3 1016 nuclei, how many of these nuclei remain after 10 min?
Determine the motor current and speed when the diverter-circuit resistance is made equal to the series-field resistance. Neglect saturation and the voltage drops across the series- field resistance as well as the armature resistance.
Following 5.0 hours of operation, the pellets are reweighed and found to have a mass of 3.52 kg. Calculate the molar flow rate (mol/h) of the feed gas and the mole fraction of water vapor in the product gas.
Combustion of table sugar produces CO2(g) and H2O(l). When 1.46 g of table sugar is combusted in a constant-volume (bomb) calorimeter, 24.00 kJ of heat is liberated.
2.8 g of N2 gas at 300 k and 20 atm was allowed to expand isothermally against a constant external pressure of 1 atm. calculate del E ,q and W for the gas.
