Butane fuel (C4H10) is burned completely with a 100 percent excess air. Determine the mole fractions of each of the products. Calculate the mass of CO2 in the products per unit mass of the fuel and the air-fuel ratio. The molar masses of C, H, O, and air are 12 kg/kmol, 1kg/kmol, 16 kg/kmol, 29 kg/kmol, respectively.

Heat is added to a piston-cylinder device filled with 2 kg of air to raise its temperature 400 c from an initial temperature of t1 27 cand pressure of pi 1 mpa. the process is isobaric process. find a)-the final pressure p2 b)-the heat transfer to the air.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.
