Amixture of n-hexane vapor and air leaves a solvent recovery unit and flows through a 70 cm diameter duct at a velocity of 3.00 m/s. at a sampling point in the duct the temperature is 40 c, the pressure is 850 mm hg, and the dew point of the sampled gas is 25 c. the gas is fed to a condenser in which it is cooled at constant pressure, condensing 60% of the hexane in the feed. a) perform a degree-of-freedom analysis to show that enough information is available to calculate the required condenser outlet temperature (c) and cooling rate (kw).b) perform the calculations to acquire the required condenser outlet temperature (c) and cooling rate (kw).

explanation:

since this is put under health, i would define "ethical (medical) behavior" the way the oath for doctors is recited.   "first do no harm."

but the term in general means when given a choice between right and wrong, we should always choose right. if we do, then we are practicing ethical behavior.

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

every chemical equation adheres to the law of conservation of mass, which states that matter cannot be created or destroyed. therefore, there must be the same number of atoms of each element on each side of a chemical equation.
