An ammonia compressor has a 5% clearance volume and displacement rate of 80 l/s and pumps against a condensing temperature of 40°c. for two different temperatures of -10°c and 10°c, compute the mass flow rate of refrigerant assuming the clearance volumetric efficiency applies. discharge specific volume corresponding to-10°c and 10°c are 112.5 l/kg and 95 l/kg, respectively.

At what temperature does the mole fraction of no reach 0.010 for the equilibrium products resulting from the combustion of gasoline and air at 1.0 and 5000 kpa?

Aflow moves in the x direction with a velocity of 10 m/s from 0 to 0.1 second and then reverses direction with the same speed from 0.1 to 0.2 second. sketch the pathline strating from x-0 and the streak! ine with dye introduced at x=0. show the streamlines for the first time interval and the second time interval.
