B) A wattmeter has a current coil of 0.032 resistance and a pressure coil of 6000 22 resistance. Calculate the percentage error if the wattmeter is so connected that
(i) the current coil is on the load side, and
(ii) the pressure coil is on the load side. The load takes 20 A at a voltage of 220 V a:d
0.6 power factor in each side.

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.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

Burgers vector is generally parallel to the dislocation line. a)-true b)-false
