Carbon dioxide (co2) at 1 bar, 300 k enters a compressor operating at steady state and is compressed adiabatically to an exit state of 10 bar, 520 k. the co2 is modeled as an ideal gas, and kinetic and potential energy effects are negligible. for the compressor, determine: (a) the work input, in kj per kg of co2 flowing, (b) the rate of entropy production, in kj/k per kg of co2 flowing, and (c) the percent isentropic compressor efficiency.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
