Question 3 (6 points) a problem of practical concern which was considered by newton and a number of other pioneers of calculus was the volume of a wine barrel. in this question, we will instead consider the related question of how much work is needed to pump wine from a barrel. suppose we have a barrel, 4 feet tall, which is positioned with its base at y = β2 and its top at y = 2. suppose in addition that the radius of the circular slice of the barrel at height y is 2 β y 2 8 . how much work is needed to pump a full barrel of wine out a spout in the top of the barrel? (a) (3 points) set up an integral to compute the necessary work. you may use g to denote the acceleration due to gravity and d to denote the density of wine.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.
