Plot the following continuous process on the blank Stuve Diagram An air sample with an initial temperature of 20 degrees Celsius at 1000 mb, is moved: (1) isothermally from 1000 mb to 850 mb, then (2) dry adiabatically from 850 mb to 600 mb, then (3) saturated adiabatically from 600 mb to 500 mb, then (4) isobarically to -40 degrees Celsius, then (5) isothermally to 400 mb.

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.
