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 & explanation:
"the force on a cutting tool are 2600n vertically downward" sounds a little unusual, since most of the time, the tool is above the object to be cut in such a way that the force acting "on the tool" is upwards. we will accept the statement as it is (downwards).
since the two forces are acting at right angles to each other, the resultant can be found using pythagoras theorem, namely
resultant = sqrt(2600^2+2100^2) = 3342 n (approx.)
the angle can be found using the arctangent function, or
angle = arctangent(2600/2100) = 51.07 degrees below the horizontal, since the 2600 n force is acting downwards.
