A 2 m long rectangular duct with a cross section 80 mm x 125 mm, is maintained at a constant surface temperature of 425 K. Air, at 1 atm and 310 K, flows into the duct with a mass flow rate of 0.08 kg/s. Calculate the heat transfer rate to the air from the duct and the air outlet temperature. Estimate Tm

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 mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
