A good way of ensuring whether a listener has understood a presentation is to record all major and minor details. identify all unknown words and phrases. rewrite the entire presentation. summarize in one’s own words.

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.

Consider a beam traveling through diamond and impinging upon the diamond-air interface. the critical angle of incidence for total internal reflection to occur is closest to the following value: select one: a)-22.50° b)-23.85 c)-24.30 d)-23.40° e)-none of the above

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.
