(a) Describe a possible method to estimate the activation energy of densification during liquid phase sintering.
(b) What are the assumptions you made for the estimation?
(c) What is the activation energy of densification in the pore filling theory?
The signpost of a fast food restaurant consists of a hollow steel cylinder of height h, inside diameter d, and outside diameter D, fixed to the ground and carries a concentrated mass M at the top.
Argon is contained in a 1 L piston-cylinder device at T=300 K and P=100 kPa. Heat is added and the volume is allowed to expand at constant pressure. If the final temperature is 400 K, find the heat added. Assume a constant specific heat capacity. Exp..
A single crystal boule of silicon is grown by the Czochralski process to an average diameter of 320 mm with length = 1500 mm. The seed and tang ends are removed, which reduces the length to 1150 mm.
an air compressor takes air from outdoors at 28deg c and 101.2kpa and compresses it to 790kpa and 50 deg c. the air
A piston-cylinder assembly contains 1 lb of Refrigerant 134a initially as saturated vapor at 10°F. The refrigerant is compressed adiabatically to a final volume of 0.8 ft3. Determine if it is possible for the pressure of the refrigerant at the fi..
