Two airstreams are mixed stea percent relative humidity retreams are mixed steadily and adiabatically. the first stream enters at 35°c and 30 ont relative humidity at a rate of 15 m /min, while the second stream enters at 12c and 90 nt relative humidity at a rate of 25 m/min. assuming that the mixing process occurs at a pressure of 1 atm, determine: (a) the specific humidity the relative humidity the dry bulb temperature, and (d) the volume flow rate of the mixture

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

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
