- Please answer this within 30 mins ! I will upvote !It says that this is wrongRequired information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. A 0.051-m³ rigid tank initially contains refrigerant-134a at 0.8 MPa and 100 percent quality. The tank is connected by a valve to a supply line that carries refrigerant-134a at 1.2 MPa and 40°C. Now the valve is opened, and the refrigerant is allowed to enter the tank. The valve is closed when it is observed that the tank contains saturated liquid at 1.2 MPa. The properties of refrigerant are ₁ = 0.02565 m³/kg, u₁ = 246.82 kJ/kg, 2 = 0.0008935 m³/kg, u2 = 116.72 kJ/kg, and h;= 108.28 kJ/kg. Determine the mass of the refrigerant that has entered the tank. (You must provide an answer before moving on to the next part.) The mass of the refrigerant is kg.
