Asquare fin with sides of length t=1 cm, overall length l.6 cm, and thermal conductivity k=10 w/rn-k is subjected to convection (h=40 w/m2-k, t,•=20°c) around its surface, including the tip. it is also generating energy (4.2x10' w/m') uniformly throughout its volume. the fin has a constant base temperature th=40°c. use the finite difference method with 5 nodes to estimate t(x). plot t(x) from the base (x=0) to the tip (x= how would your graph change if q'=o (no internal generation)?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

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.
