It consists of a tube with a small opening facing the oncoming fluid, and a second opening perpendicular to the first. The stagnation pressure is the pressure at the point where the fluid comes to a complete stop, and it <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> is equal to the sum of the static pressure and the dynamic pressure.<\/p>\n<p>The static pressure is the pressure of the fluid at rest. It can be measured by a simple pressure gauge. The dynamic pressure is the pressure due to the motion of the fluid. It can be calculated from the Bernoulli equation, which states that the total energy of a fluid is constant.<\/p>\n<p>The pitot tube is used in a variety of applications, including aircraft flight
