Propane is burned in a furnace using air as an oxygen source. For this question we will assume that air is 20% O2 and 80% N2. The flow rate of the air provides a 60% fractional excess of oxygen which allows for complete consumption of the propane. The inlet feed of air and propane to the furnace is at a temperature of 45 [C]. Assume a propane flow rate of 1 mol/min and answer the following questions. Required:
a. Taking a basis of 100 mol C3H8, find amount of air fed at 25% excess.
b. Find the amount (moles) of stack gas.
c. Find the composition of CO2.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence

aquifers are bounded above and below by impermeable rock. the driving force of groundwater movement in confined aquifers is pressure, rather than gravity.

i don,t know so just answer mine

most historians agree that gabriel mouton, the vicar of st. paul’s church in lyons, france, is the “founding father” of the metric system. he proposed a decimal system of measurement in 1670. mouton based it on the length of one minute of arc of a great circle of the earth (now called a nautical mile, 1852 meters). he also proposed the swing-length of a pendulum with a frequency of one beat per second as the unit of length (about 25 cm). a pendulum beating with this length would have been fairly easy to produce, thus facilitating the widespread distribution of uniform standards. over the years, his work was revised, improved, and extended by a number of french scientists.

the political sponsor of weights and measures reform in the french revolutionary national assembly was the bishop of autun, better known as talleyrand. under his auspices, the french academy appointed several committees to carry out the work of developing a usable system of weights and measures for france. one of the committees recommended a decimalized measurement system based upon a length equal to one ten-millionth of the length of a quadrant of the earth’s meridian (i.e., one ten-millionth of the distance between the equator and the north pole).
