C8H18is burned with 100 percent excess air in a rigid adiabatic container (i. e., closed system). Initially, the mixture is at 1 atm and 25 °C. (30 pt.)(a)Determine the pressure after the combustion process.(b)Determine the temperature after the combustion process.(c)Determine the total exergy destruction per unit mass of the combustion process. You may assume T0=298 K

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.

What is creep? what is stress relaxation?

Abarometer contains mercury with a density of 13600 kg/m3. atmospheric conditions are 95.8 kpa and 20 °c at 20 °c, the vapor pressure of the mercury is 0.000173 kpa. the column of mercury will rise to a height of most nearly. select one: a)- 0.38 m b)- 0.82 m c)- 0.48 m d)- 0.72 m
