Question 1: a) A rigid insulated tank of 3m3 volume contains saturated steam at 100C and 1atm. This tank is connected to a line carrying superheated steam at 3MPa and 300C. When the steam pressure inside the tank rises to 3MPa the line is closed to have a saturated steam inside. Determine the mass of steam inside the tank at the end of the process and also calculate the mass of steam entered the tank during the process. [5+2]
