Figure 8 illustrates the measured total pressure loss for System Section #1A as a function of the velocity pressure upstream of the test section (based on standard conditions of air density); the resulting system loss coefficient is C = 6.048.
The temperatures used in this study were: 200, 220, 230 and 240AdegC at a total pressure of 200 psi.
It shows an improvement of both total pressure ratio (by 5.3%) and isentropic efficiency (by 1.9%).
Since the cross sectional area of the plenum is much larger than the cross sectional area of the inlet to the impeller, the velocity in the plenum is relatively small and the dynamic pressure ([[rho]v.sup.2]/2) is negligible compared to the total pressure, meaning that the static and total pressures can be considered equal in the plenum.
By putting the total pressure equal to zero, required air was injected into the system through aerator.
