# A50 mol% mixture of propane (1) and n-butane (2) enters an isothermal flash drum at 37°c. if the flash drum is maintained at 0.6 mpa, what fraction of the feed exits as liquid? what are the compositions of the phases exiting the flash drum? work the problem in the following two ways. a. use raoult’s law (use the peng-robinson equation to calculate pure component vapor pressures). b. assume ideal mixtures of vapor and liquid. (use the peng-robinson equation to obtain fsat for each component.)   ### Another question on Engineering Engineering, 03.07.2019 12:20

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct Engineering, 04.07.2019 17:20
Sketch the tensile stress versus strain curve for a typical ceramic material. compare this curve with that for a typical metallic material and explain the major difference between the two curves. how, in principle, can the strength of a ceramic material be increased? why is the compressive strength higher than the tensile strength for ceramic materials?
