30,000 hp (22 MW) or 57 percent of the total turbine shaft power, and it generated over 1,500 lb/in2 (10 MPa) of pressure rise.

• The fuel (RP1) pump, being in the middle of the turbopump assembly, had to take in the 15,640 gpm (0.99 m3/s) of RP1 through a side inlet piping configuration, which generally results in less .^..-capability than axial inlet piping. Here the inducer is larger and the flow rate lower than for the liquid oxygen pump, creating the potential for higher N.; yet it ended up being lower, namely Nss = 34,200 (ùss = 12.5). Nonetheless, this enabled the RP1 pump to operate at a static inlet pressure as low as 16 lb/in2 (0.11 MPa) above the (negligible) vapor pressure of this liquid. With specific speed Ns just over 1,100 (0.40), this pump consumed the remaining turbine shaft power of 22,700 hp (17 MW) and generated a pressure rise of just over 1,800 lb/in2 (12.4 MPa).

• Throughout the burn, these pumps deviated no more than about 8 percent from the design value of Q/N; that is, the flow coefficient was essentially constant. Thus, this turbopump did not suffer from the off-design low-flow conditions of most commercial, industrial pumps, as described in Section 2.1 and Subsection 2.3.2, including those of high energy level, which made it a little easier for this machine to operate at high energy levels.
