Astrain gauge that has a nominal resistance of 350 w and a gauge factor of 1.8 is mounted in an equal-arm wheatstone bridge (equal-arm means that the other 3 resistors also have a 350 w resistance. these 3 resistors are not strain gauges). this strain gauge is mounted to sense axial strain. the bridge output voltage is 1 mv and the input voltage is 5 v. what is the axial strain measured by the strain gauge? if we also have strain in the transverse direction (perpendicular to the axial direction) and this strain is 15% of the axial one, what is the error in the previous axial strain due to a transverse sensitivity of the gauge of 0.05? the gauge factor of 1.8 was obtained from a tensile test on a steel specimen (poisson’s ratio = 0.27).

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.

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.
