Problem 1: A sealed tank contains saturated steam at 5 bar. The volume of the tank is1m3. a) Heat is added until the pressure in the tank pressure doubles. What is the final temperature? b) Calculate the necessary amount of heat.
Problem 2: A sealed pressure cooker contains steam at 5 bar and 200 °C. Subsequently, the cooker is cooled until the contents become saturated vapor. a) What is the final temperature? b) How much heat is removed during the cooling step? c) How much additional heat must be removed in order to completely condense the steam in the cooker and produce saturated liquid?
