Outlet pressures of centrifugal pump versus time.

𝑇 (s)	𝑃𝑙𝑢 (MPa)	𝑡 (s)	𝑃𝑙𝑢 (MPa)	𝑡 (s)	𝑃𝑙𝑢 (MPa)
272	0.07	833	0.47	1345	0.87
376	0.12	890	0.52	1408	0.92
442	0.17	962	0.57	1460	0.97
504	0.22	1023	0.62	1524	1.02
582	0.27	1085	0.67	1590	1.07
646	0.32	1148	0.72	1640	1.12
702	0.37	1213	0.77	1705	1.17
770	0.42	1285	0.82	1764	1.19

Note: 𝑃_𝑙𝑢 is the outlet pressure of the centrifugal pump, which is 1.19 MPa when the valve is fully closed.
