  2. Pitot tube - Wikipedia

    en.wikipedia.org/wiki/Pitot_tube

    The pitot tube can be inserted through a small hole in the duct with the pitot connected to a U-tube water gauge or some other differential pressure gauge for determining the flow velocity inside the ducted wind tunnel. One use of this technique is to determine the volume of air that is being delivered to a conditioned space.

    The pitot tube supplies pressure to the airspeed indicator. Pitot pressure is equal to stagnation pressure providing the pitot tube is aligned with the local airflow, it is located outside the boundary layer, and outside the wash from the propeller.

    Pitot intake operating modes. Pitot inlets are used for subsonic aircraft. A pitot inlet is little more than a tube with an aerodynamic fairing around it. When an aircraft is not moving, and there is no wind, air approaches the intake from all directions: directly ahead, from the side, and from behind.

    en.wikipedia.org/wiki/Pitot–static_system

    The pitot pressure is obtained from the pitot tube.The pitot pressure is a measure of ram air pressure (the air pressure created by vehicle motion or the air ramming into the tube), which, under ideal conditions, is equal to stagnation pressure, also called total pressure.

  6. Tubular heart - Wikipedia

    en.wikipedia.org/wiki/Tubular_heart

    The tubular heart or primitive heart tube is the earliest stage of heart development. [1] The heart is the first organ to develop during human embryonic development. [2]From the inflow to the outflow, the tubular heart consists of sinus venosus, primitive atrium, the primitive ventricle, the bulbus cordis, and truncus arteriosus. [3]

  7. Pitot pressure - Wikipedia

    en.wikipedia.org/wiki/Pitot_pressure

    The stationary fluid can be connected to a pressure-measuring device, or used in various devices. For subsonic flow, pitot pressure is equal to the stagnation pressure (or total pressure) of the flow, and hence the term pitot pressure is often used interchangeably with these other terms. For supersonic flow, however, pitot pressure is the ...

  8. Heart development - Wikipedia

    en.wikipedia.org/wiki/Heart_development

    Heart development, also known as cardiogenesis, refers to the prenatal development of the heart. This begins with the formation of two endocardial tubes which merge to form the tubular heart, also called the primitive heart tube. The heart is the first functional organ in vertebrate embryos.

    en.wikipedia.org/wiki/Henri_Pitot

    Henri Pitot (French: [ɑ̃ʁi pito]; May 3, 1695 – December 27, 1771) was a French hydraulic engineer and the inventor of the pitot tube. In a pitot tube, the height of the fluid column is proportional to the square of the velocity of the fluid at the depth of the inlet to the pitot tube. This relationship was discovered by Henri Pitot in ...
