Ecuaci\u00f3n: Presi\u00f3n en una columna de fluido<\/h3><\/div>

La ecuaci\u00f3n utilizada para describir la presi\u00f3n ejercida por la masa de un gas o un l\u00edquido en una columna es:<\/h3><\/div>
<\/div><\/div><\/span>

P = \u03c1gh<\/em><\/h2><\/span>
<\/div><\/div><\/div>

    \n
  • P<\/em><\/strong> es la presi\u00f3n,<\/li>\n
  • \u03c1 <\/em><\/strong>es la densidad del fluido,<\/li>\n
  • g<\/em><\/strong> es la aceleraci\u00f3n de la gravedad (9,81 m\/s2 para la Tierra)<\/li>\n
  • h<\/em><\/strong> es la altura del punto considerado.<\/li>\n<\/ul><\/h3><\/div>

    En esta imagen queremos representar que 1 Atm\u00f3sfera equivale a una presi\u00f3n de una columna de :<\/p>\n

    • 760<\/strong> mmHg (mil\u00edmetros de mercurio).<\/li>\n<\/ul>\n

      El agua es un elemento qu\u00edmico con el s\u00edmbolo H2O<\/strong><\/p>\n

      En nuestra industria se ocupa de manera muy frecuente los mil\u00edmetros de mercurio mmHg<\/strong> o pulgadas de mercurio inHg<\/strong> sobre todo cuando queremos hablar en Presi\u00f3n Absoluta<\/strong><\/p><\/h3><\/div>
