Awell-insulated, rigid vessel is divided into two compartments by a partition. the volume of each compartment is 0.1 m3. one compartment initially contains 400 moles of gas a at 300k, and the other compartment is initially evacuated. the partition is then removed and the gas is allowed to equilibrate. gas a is not ideal under these circumstances but can be described well by the following equation of state: p=rt/(vm-b)-a/(tvm2) with constants a=40 [(j k m3)/mol2] and b=3 x 10-5 m3/mol you may take the ideal gas heat capacity of gas to be cv, mideal=3r/2. calculate the final temperature.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

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.

Adouble-strand no. 60 roller chain is used to transmit power between a 13-tooth driving sprocket rotating at 300 rev/min and a 52-tooth driven sprocket. a) what is the allowable horsepower of this drive? b) estimate the center-to-center distance if the chain length is 82 pitches. c) estimate the torque and bending force on the driving shaft by the chain if the actual horsepower transmitted is 30 percent less than the corrected (allowable) power.
