Question: Problem 1. (15') A closed rigid tank whose volume is 1.5 m' contains Refrigerant 134a, initially a two phase liquid vapor mixture at 10 C.

Problem 1. (15') A closed rigid tank whose volume is 1.5 m' contains Refrigerant 134a, initially a two phase liquid vapor mixture at 10 "C. The refrigerant is heated to a final state where temperature is 50 "C and quality is 100%. Locate the initial and final states on a sketch of the T - v diagram. Determine the mass of vapor present at the initial and final states, each in kg
