A methane stream at 25°Cand 10 atm is fed to a combustion furnace at a rate of 0.05 m^3/s. Air is added to the furnace at a rate of 7.0 m^3/s at 100°C and 1 atm. All of the methane fed to the furnace is combusted, but 10% of the methane fed is converted to CO instead of CO2. Assume ideal gas behavior.
a. Write and balance the combustion reaction(s) that are taking place,
b. Draw a process flowchart, label the unknown variables and fully balance the process.
c. What is the percent excess air fed to the furnace? (A:~~18%)

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
