An equimolar liquid mixture of n-pentane and n-hexane at 80°c and 5 atm is fed into a flash evaporator at 100.0 mol/s. when the feed is exposed evaporator, a substantial amount is vapourized. the temperature in the tank is maintained at 65°c by adding heat. the vapour and liquid phases, which are in equilibrium with each to a reduced pressure in the as separate streams. the liquid product stream contains separated and discharged other, are 41 mole% petaie, determine: the system pressure in atmospheres, (10 points) b. the composition of the vapour stream, (10 points) c. the fraction of the propane that is vapourized. (10 points) a. pent

In meteorology, a  cloud  is an aerosol consisting of a visible mass of minute liquid droplets, frozen crystals, or other particles suspended in the atmosphere of a planetary body. nephology is the science of  clouds, which is undertaken in the  cloud  physics branch of meteorology.cirrus clouds  usually describe clouds high in the atmosphere that can include wispy clouds, typically with ice crystals. variations include cirrus, cirrocumulus and cirrostratus as defined by the cloud's position in the atmosphere.layered stratus clouds  have both flat tops and bases, and can appear as if they take up the whole sky, stretching from horizon to horizon. other combinations and variations include stratus, stratocumulus, nimbostratus and altostratus.cumulus clouds  often pile up in multiple layers of the atmosphere, representing clouds that develop vertically. cumulus clouds often look like pillars with anvil-type tops or columns of clouds stacked vertically. variations include cumulus, cumulus-congestus, cumulonimbus and altocumulus.
