Both a gage and a manometer are attached to a gas tank to measure its pressure. if the reading on the pressure gage is 130 kpa, determine the distance between the two fluid levels of the manometer if the fluid is:
(a) mercury with density 13,600 kg/m^3 or
(b) water with density 1000 kg/m^3

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.

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

An air compression refrigeration system is to have an air pressure of 100 psia in the brine tank and an allowable air temperature increase of 60°f for standard vapor compression cycle temperatures of 77 f entering the expansion cylinder and 14 f entering the compression cylinder, calculate the coefficient of performance a. 2.5 b 3.3 c. 4.0 d. 5.0
