A50 mol% mixture of propane (1) and n-butane (2) enters an isothermal flash drum at 37°c. if the flash drum is maintained at 0.6 mpa, what fraction of the feed exits as liquid? what are the compositions of the phases exiting the flash drum?
work the problem in the following two ways.
a. use raoult’s law (use the peng-robinson equation to calculate pure component vapor pressures).
b. assume ideal mixtures of vapor and liquid. (use the peng-robinson equation to obtain fsat for each component.)
answer with explanation:
when dealing with heavy loads, one needs to take certain precautions in order to avoid or prevent from injuries.
for instance, one should avoid lifting above the shoulder level which can end up pulling your muscle.
also, you can either break the load in parts if possible or get some for lifting heavy bulks.
moreover, one should try to lift with the legs while keeping the back straight and not twisting it.
