Thermodynamics: A rigid cylinder is filled with refrigerant-134a at 18°C. At this state, 40 percent of the mass is vapor. A valve at the bottom is opened, and refrigerant is withdrawn outside.Heat is transferred to the tank such that the temperature in the tank remains constant and the refrigerant fills the tank all the time (V1= V2). Determine the amount of heat that must be transferred by the time one-fourth of the total mass has been withdrawn. The tank volume is 0.1-m3. Clearly show work.
