C3Hy is burned completely with excess air to form CO2 and H20. If feed is 20 kg of C3H8 and 400 kg of Air
44 Kg of CO2 and some of CO produced
a. What is the percentage excess air?
b. Using atomic balance find the Orsat analysis of the flue gas.
c. What is the fractional conversion of C3Hg to CO?

1in2 processor chip can be modelled as an isothermal plane wall of silicon, isothermal on both sides. the power input to the bottom of the plane wall, or the processing power of the chip, often called the thermal design power (tdp), is 100w. assume the periphery is adiabatic. the silicon is 400 microns thick. the temperature at the junction, or in this case on the bottom of the isothermal plane wall, is 85°c. what is the top surface temperature, assuming that the only mode of heat transfer is conduction
