Agas mixture containing 85.0 mole% n2 and the balance n n-hexane flows through a pipe at a rate of 100.0 m3/h. the pressure is 2.00 atm absolute and the temperature is 100°c. what is the molar flow rate of the gas in kmol/h? is the gas saturated? if not, to what temperature (°c) would it have to be cooled at constant pressure in order to begin condensing hexane? to what temperature (°c) would the gas have to be cooled at constant pressure in order to condense 80% of the hexane?

Amass m = 74 kg slides on a frictionless track that has a drop, followed by a loop-the-loop with radius r = 18.4 m and finally a flat straight section at the same height as the center of the loop (18.4 m off the ground). since the mass would not make it around the loop if released from the height of the top of the loop (do you know why? ) it must be released above the top of the loop-the-loop height. (assume the mass never leaves the smooth track at any point on its path.) 1. what is the minimum speed the block must have at the top of the loop to make it around the loop-the-loop without leaving the track? 2. what height above the ground must the mass begin to make it around the loop-the-loop? 3. if the mass has just enough speed to make it around the loop without leaving the track, what will its speed be at the bottom of the loop? 4. if the mass has just enough speed to make it around the loop without leaving the track, what is its speed at the final flat level (18.4 m off the ground)? 5. now a spring with spring constant k = 15600 n/m is used on the final flat surface to stop the mass. how far does the spring compress?
