Example 2: Consider constant pressure complete combustion of stoichiometric liquid octane-air and octane air with 10% excess air mixture initially at 298K and 1 atm. Compare the adiabatic flame temperature vlaues.

2. (a)A single thick-walled cylinder h2as an inner radius of 100 mm and an outer radius of 155 mm. The cylinder is subjected to an internal pre2 ssure of 65 ????/?? and an external pressure of 25????/?? . (i) Calculate the hoop and radial stress inside and outside of the cylinder. (ii) Sketch the 3D Mohr’s Circle of a point on the inner surface of the cylinder and label the principal stresses (include coordinates values). (iii) If the cylinder is made of a copper alloy with yield strength of 200 MPa; verify whether the cylinder will fail using the Von Mises Criteria and calculate the Factor of Safety. (b) To increase the FOS to the standards value, another cylinder is shrunk-fitted to make a compound cylinder. When the internal pressure load remains unchanged, the maximum hoop stress in the inner cylinder of the compound cylinder has been found to be reduced by 5% of the original value(i)Calculate the interface pressure at the common radius of the compound cylinder.  (ii)Assume the…
