Carbon tetrachloride flows with a velocity of 0.30 m/s through a 30-mm-diameter tube. a model of this system is to be developed using standard air as the model fluid. the air velocity is to be 2 m/s. what tube diameter is required for the model if dynamic similarity is to be maintained between model and prototype?

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

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
