Convert the bearings in problems 7.8 through 7.9 to azimuths from north and compute the angle, smaller than 180 degree, between successive bearings. n44 degree 50'38"e, s38 degree 42'54"e, s45 degree 06'02"w, and n13 degree 24"30"w n32 degree 42'38"e, s54 degree 02'02"e, s22 degree 42'56"w, and n44 degree 35'26"w

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.

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.
