3. A well-insulated, 65-m³ storage tank contains 220 L of liquid water at 75°C. The rest of the

tank contains steam in equilibrium with the water. Spent process steam at 2.3 bar and 91%

quality enters the tank until the pressure is the tank reaches 2.3 bar. Assume no heat

losses. How much steam enters the tank, and what is the amount of liquid water present at

the end of the process?
