Find the convection coefficient (h) associated with airflow over the surface of a thick, stainless steel casting. thermocouples are inserted into the casting at distances of 10 mm and 20mm from the surface along a hypothetical line normal to the surface. the steel has a thermal conductivity of 15 w/m-k. the therm

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
