Question

A water-filled reactor with volume of 1 m3 is at 20 MPa, 360°C and placed inside a containment room as shown in Fig. P5.48. The room is well insulated and initially evacuated. Due to a failure, the reactor ruptures and the water fill the containment room. Find the minimum room volume so the final pressure does not exceed 200 kPa.

David · Accepted Answer

Given 
P = 20 MPa 
V = 1m3 
T = 360*C 
 
 
Since room is well insulated 
 
No exchange of mass and energy 
 
Q = dE + W 
dE = 0 
E = constant 
H1=H2 
U1 + P1V1 = U2 + P2V2 
P1V1 = P2V2 
V2 = 10 m
