Gas-liquid separators are important in industry. Size a vertical liquid-vapor separator for removing water from air. The air flowrate is 600 SCFM(Standard Cubic Feet per Minute) containing 170 lb/min of water. The drum will be operated at 1.25 psi and 70 F. Do you think a horizontal tank would be larger, smaller, or the same size?
A helium-filled weather balloon has a volume of 815 L at 22 oC and 752 mmHg. It is released and rises to an altitude of 7.16 km, where the pressure is 364 mm Hg and the temperature is -25oC
Pyridine(C5H5N) is a weaker base in H2O than 2,6 lutidine (dimethylpyridine), but we observe that the pyridine-BF3 complex is more stable than the comparable lutidine-BF3. Explain the reason for this inversion in stabilities.
what fraction of this side chain is positively charged and what fraction is neutral at pH 7.2?
