While discussing the numbering of HO2S sensors, Technician A says they are identified by their position in relation to the number 1 cylinder and their location relative to the converters. Technician B says HO2S sensors on the same side of the vehicle as the number 1 cylinder have a 1 prefix, and sensors mounted downstream from the converter have a 1 suffix. 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.
