A computer program for an equation of wind velocity profiles from zero to thirty feet
… Velocity measurements were made with four pitot tubes mounted on a thirty-foot mast at intervals of eight feet along the mast. Velocity pressures were recorded instantaneously from all the pitot tubes by an oscillograph. The data recorded were entered into a computer program for multiple …

Development and testing of experimental equipment to measure pore pressure and dynamic pressure at points outside a pipe leak
… and the measurement instruments, which were Pitot tubes. When using the experimental setup, pore pressures and dynamic pressures around the leak and therefore within the ballotini bed were measured using two Pitot tubes. The accuracy and repeatability of these measurements were also of …

The flow about a slender propellor-driven body in a temperature stratified fluid
… measurements were taken using thermocouples and pitot tubes of various size, a yawhead probe, a cross-wire hot-wire, and a straight-wire hot-wire as appropriate. For measuring the temperature fluctuations, the straight hot-wire probe was operated in the low-overheat mode to maximize temperature …

Visualising convective heat transfer in a propagating wildland fire
… quantify heat transfer dynamics. Thermocouples, Pitot tubes, and heat flux sensors were used to capture physical measurements for validation. The results reveal that convective heating dominates in wind-driven and sloped scenarios, while convective cooling plays a critical offsetting role in …

Some aspects of magnetohydrodynamics
… of the theoretical limitations on the use of Pitot tubes and electric potential (e.p.) probes in MHD flows, and provide some estimates of the errors to be expected. In chapter 5 we analyse the stability of parallel flows in parallel magnetic fields and also some aspects of the stability of the …

An Archival Analysis of Stall Warning System Effectiveness During Airborne Icing Encounters
… and icing-induced system issues (such as frozen pitot tubes), which compromised stall warning system effectiveness and airframe envelope protections. Each of these sources of missed stall warnings could be addressed by Aerodynamic Performance Monitoring (APM) systems that directly measure the …

A laboratory investigation of the effect of flow rate and bedding characteristics on the interaction of a vertical water jet with an idealised soil medium
… the water jet required for the pipe leak and, a Pitot tube positioning system above the tank allowed for positioning of straight and L-type Pitot tubes in the granular bed, which were used to measure the leakage conditions within the bed. Results from the experiments revealed that the soil-leak …

Advanced experimental modelling of hydrodynamic and aerodynamic wakes in floating offshore wind turbines using particle image velocimetry
… wave basin instruments—such as wave probes, pitot tubes, acoustic and laser doppler velocimeters—are insufficient for capturing the flow velocity characteristics necessary to measure parameters like pressure distributions, Reynolds stresses, turbulent kinetic energy (TKE), and turbulent …
