Saturated water vapor at 350 degrees C is heated at constant pressure until its volume has doubled. Determine the final temperature using (a) the ideal gas equation of state (b) the compresability charts and (c) the steam tables

a) T = K

b) T = K

c) T = K

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m

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.

What is the heat treatment of metals? what is the benefit of it? why and how it's useful? answer in details, do not write by hand.
