The pitot tubes at Stations I, V, and VI could be extended from 0 to 24 inches in a direction approximately normal to the hull surface. The pitot tubes at Stations II and III could be extended from 0 to 18 inches. (Station IV was a conventional Prandtl tube located in the throat of the condenser scoop.) The tangent planes to the hull surface at the measuring stations were approximately parallel to the axis of the vessel. Thus, the pitot tubes were extended in a direction normal to this axis. The direction of flow (in planes perpendicular to the pitot tube) was measured at each extension of the pitot tube by rotating the tube until equal static pressures were obtained at the two static holes. The static pressures were indicated on a manometer located near each of the pitot-tube stations to facilitate making the directional measurements. The flow direction was measured from a line parallel to the center- line of the vessel. After the pitot tube had been aligned with the flow, valves were adjusted to transmit the static pressure and total pressure to a centrally located manometer board. A velocity and direction calibration was made at the Model Basin b
