Ay-connected of three identical 100-kva 7967/277 v transformers is supplied with power directly from a large constant-voltage bus. in the short-circuit test, the recorded values on the high- voltage side for one of these transformers are: vsc = 560 v isc = 12.6 a psc = 3300 w (a) if this bank delivers a rated load at 0.88 pf lagging and rated voltage, what is the line-to-line voltage on the primary of the transformer bank? (b) what is the voltage regulation under these conditions?

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

A2-m rigid tank initially contains saturated water vapor at 100 kpa. the tank is connected to a supply line through a valve. steam is flowing in the supply line at 600 kpa and 300 c. the valve is opened, and steam is allowed to enter the tank until the pressure in the tank reaches the line pressure, at which point the valve is closed. a thermometer placed in the tank indicates that the temperature at the final state is 200°c. determine (a) the mass of steam that has entered the tank (b) the amount of heat transfer.
