A class 2 estimate of the ISBL capital cost of building a 200,000 MMlb/yr ethylene cracking plant has been stated as $850 MM -5%/+10%. The plant is to be built as an expansion of an existing site and offsite costs are estimated to be between $170 MM and $250 MM. Estimate a value for the total project cost that will give 98% confidence that the project can be carried out within the amount estimated.
How much transmit power is required (disregarding power losses at transmitter and receiver ends) for a maximum BER of 10-5, when using:a. Coherently detected BPSKb. By how much must transmit power be increased to maintain the maximum BER of 10-5 if t..
A steam turbine generates 800 kW of work by expanding steam from 50 bar, 400 °C to 1 bar. At the exit of the turbine the steam contains 2% moisture.
Figure shows an x-ray diffraction pattern for a-iron taken using a diffract meter and monochromatic x-radiation having a wavelength of 0.1542 nm; each diffraction peak on the pattern has been indexed.
Calculate the volumetric coefficient of thermal expansion of acetone at 20 °C and the percent increase in volume upon a temperature increase from 20 °Cto30 °C at constant pressure.
When the valve is quarter open, what fraction of the pump work is lost across the valve?
One mol of methanol vapor is cooled under constant pressure in a closed system by removing 25000 J of heat. Initially, the system is at 2 bar, 200 °C. Determine the final temperature.
Here you compare the value of H when you use actual data (steam tables) and when you assume ideal gas. Reference means H = 0. State all reasonable assumptions. Vapor-liquid phase partitioning is involved.
Hydrogen chloride gas, produced by burning chlorine with hydrogen, is required at a supply pressure of 600 kN/m2, gauge. The pressure can be achieved by either operating the burner under pressure or by compressing the hydrogen chloride gas.
Aniline is produced by the hydrogenation of nitrobenzene. The reaction takes place in a fluidized bed reactor operating at 270 °C and 20 bar. The excess heat of reaction is removed by a heat transfer fluid passing through tubes in the fluidized be..
calculate the overall material balance as well as the chemical species
A vapour stream that is 65 mole% styrene and 35 mole% toluene is in equilibrium with a liquid mixture of the same two species. The pressure in the system is 20 kPa. Use Raoult's law to estimate the composition of the liquid and the system temperat..
What mass of ethylene glycol, HOCH2CH2OH, must be dissolved in 4.510 kg of water to result in a freezing point of 18.0°C? What is the boiling point of the same solution?
