pitot tube造句
1 Pitot tube is often used to measure airflow rate while fan performance test is carried out by the outlet test duct. 2 A new half-tube averaging pitot tube is designed, and based on the Bernolli equation and continuity equation, a mathematics model is established. 3 Pressure and velocity profiles are measured with Pitot tube, Pitot-column and Pitot-sphere, respectively. And their distributions as well as secondary flow in upper and lower elbows are given. 4 Spiral groove parameter, oil quantity up through pitot tube and bearing clearance are the main factors that influence lubricating reliability of oil-lubricated guide bearings. 5 TORBAR averaging pitot tube is a flow sensor of new detecting section. 6 Choose the NDIR air analysis apparatus and Pitot tube using in the CEMS (continuous emission monitoring system) which are more suitable for plants'environment and more precise. 7 It also discusses the location and installation of Pitot tube and introduces the way to determine the average flow rate from the central flow rate inside a pipe measured by the Pitot tube. 8 In most turbulent flows, for example, only the mean velocity can be measured with a Pitot tube. 9 To overcome the flow fields disturbance difficulties of the regulating valve in flow measurement and test, the fluid disturbance distribution in the pipeline was studied with the pitot tube. 10 In particular, they were reviewing the performance of a Pitot tube, part of the speed measurement system. 11 At high altitude and low temperatures, water sometimes doesn't freeze. Instead, it hovers, but as soon as something solid — like a pitot tube — flies through it, the water flash-freezes to form ice. 12 A novel method was proposed based on the total pressure of pitot tube and power spectral density (PSD). 13 A novel method was proposed based on the total pressure of pitot tube and power spectral density. 14 The time averaged velocities in fluid flow can be measured simply and conveniently by investigating the effect of the pitot tube in supersonic flow. 15 Aiming at investigating how the air horn and mounting angle affect a Pitot tube measurement, experiments were carried out on various Pitot tubes. 16 Used in working situations, extra errors are inevitably added to the measurement results of a Pitot tube due to deviations from its standard usage conditions. 17 The principle, structure and water flow measuring formula of Venturi Pitot tube flowmeter are introduced. The simple calibration with flow method adopting field condition is also presented.
