minimum pressure is well above vapor pressure. For the lower cavitation num- 

 bers, the pressure falls below vapor pressure becoming progressively lower 

 until for the smallest cavitation number it begins to rise again toward vapor 

 pressure. The steep rise in pressures appeared to coincide roughly with the 

 "average" end of the cavities. The form of the pressure distribution for the 

 measurements in the second set from the top of Figure 2k indicates the pres- 

 ence of a stagnation point. However, the absolute magnitude of the pressures 

 are probably not correct because of the manometric system used (see Reference
