A 0.410 mol n-butane/mol, 0.590 mol propane/mol mixture at 25°C enters a furnace. In a separate stream, air enters the furnace in 10.0% excess at 171.0°C. The fuel reacts completely. Calculate the adiabatic flame temperature by following the steps below. Take 100 mol of fuel as the basis. Assume the heat capacity for O2 is 3.31 à 10-2 kJ/(mol·°C), N2 is 3.13 à 10-2 kJ/(mol·°C), H2O is 3.85 à 10-2 kJ/(mol·°C), and CO2 is 5.00 à 10-2 kJ/(mol·°C).

What is N2, the moles of air entering the furnace?

Ahouse has the following electrical appliance usage (1) single 40w lamp used for 4 hours per day (2) single 60w fan used for 12 hours per day (3) single 200w refrigerator that runs 24 hours per day with compressor run 12 hours and off 12 hours find the solar power inverter size in watt with correction factor of 1.25.

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
