Steam enters an adiabatic convergent-divergent nozzle at 0.6 MPa, 200 o C, with a velocity of 50 m/s. It expands to a pressure of 0.13 MPa to increase its velocity of 600 m/s. Determine the final temperature if the steam is superheated in the final state, and its quality if it is in the wet region.

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure

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.
