Question:

A water-filled reactor with a volume of 1 m³ is at 20 MPa and 360◦C and is placed inside a containment room, as shown in Fig. P3.101. The room is well insulated and initially evacuated. Due to a failure, the reactor ruptures and the water fills the containment room. Find the minimum room volume so that the final pressure does not exceed 200 kPa.
