Problem 11.9: Assuming the system methanol(1)/ethanol(2) to form ideal solutions, do the following: a) Calculate the bubble and dew pressure at 100 °C of a mixture that contains 20% methanol by mol. b) Construct a Pxy graph at 100 °C. c) Construct a Txy graph at 1.2 bar. d) A stream that contains a methanol/ethanol mixture with 32% mol methanol is flashed to 100 °C to a pressure such that the molar rate of the vapor stream is 75% of the feed. Determine the temperature and the composition of the two phases. The Antoine equation for the pure components are given below:
At one time, biologists thought that fungi were merely forms of plants that had lost their chlorophyll and had returned to saprotrophy to gain food. Why is this no longer considered a solid theory?
Approximately 2.0 104 gal nitric acid was spilled. Assume that the acid was an aqueous solution containing 70.0% HNO3 by mass with a density of 1.42 g/cm3. How much sodium carbonate was required for complete neutralization of the spill, and how ..
Develop the ordinary differential equations for each of the molecules in the cascade. (Each phosphorylated molecule is different from a nonphosphorylated molecule.)
determine the ratio of starting torque to full-load torque.
The feed (CAo= 1.0, CRo= 0, CSo= 0) enters two mixed reactors in series (?1= 2.5 min,?2= 10 min) knowing the composition in the first reactor (CA1= 0.4, CR1= 0.4, CS1= 0.2),find the composition leaving the second reactor (using fractional yield co..
Methanol can be manufactured by the gas phase reaction CO(g) + 2H2(g)?CH3OH(g)at 400K and 1.013 bar.The following data are available;?H298= -90.71 kJ/mol?G298= -24.33 kJ/mol.
Determine the hysteresis and eddy-current losses separately at both frequencies.
