Abstract

PARA MEDIR LA VELOCIDAD DEL FLUJO DE GAS EN DIRECCION (F) A LO LARGO DE UN TUBO (8) SE UTILIZA UN GASTOMETRO (2) QUE CONSTA DE UN SENSOR DE FLUJO DE GAS (4) CONECTADO POR MEDIO DE TUBOS (50, 52) A UNA SONDA DE PITOT DE PROMEDIACION (6) COMPUESTA DE DOS TUBOS (10) Y (12) DE CORTE TRANSVERSAL CIRCULAR DISPUESTO LADO A LADO Y CERRADO EN SUS UNICOS E IDENTICOS EXTREMOS (14 Y 16) Y MONTADA EN UNA MANGA (18) DE FORMA HERMETICA AL GAS QUE SE AJUSTA A LA APERTURA (20) QUE SE ENCUENTRA EN LA PARED DEL TUBO (8) Y ESTA UNIDA AL TUBO DE FORMA HERMETICA AL GAS. LOS DOS TUBOS (10 Y 12) SON IDENTICOS EN FORMA Y TAMAÑO Y CADA UNO DE ELLOS TIENE CUATRO AGUJEROS CIRCULARES (22) QUE PASAN A TRAVES DE LA PARED DEL TUBO. TODOS LOS AGUJEROS (22) SON DE LA MISMA FORMA Y TAMAÑO Y CADA UNO TIENE UN DIAMETRO QUE VA DE 0,4 MM A 1,00 MM. EL DIAMETRO INTERNO DE CADA TUBO (10,12) ES DE 1,59 MM COMO MINIMO Y LA RELACION DE LA ZONA DE CORTE TRANSVERSAL DE CADA TUBO (10,12) A LA ZONA DE CORTE TRANSVERSAL DE CADA AGUJERO (22) ES DE POR LO MENOS 9:1. LAS POSICIONES DE LOS AGUJEROS (22) EN UN TUBO (10,12) SON IDENTICAS A LAS POSICIONES DE LOS AGUJEROS DEL OTRO TUBO (10,12) EXCEPTO QUE LOS AGUJEROS (22) DEL TUBO (10) MIRAN DIRECTAMENTE CORRIENTE ARRIBA CON RESPECTO AL FLUJO DE GAS (F) MIENTRAS QUE LOS AGUJEROS (22) DEL TUBO (12) MIRAN DIRECTAMENTE CORRIENTE ABAJO. CON RESPECTO A UN PLANO IMAGINARIO (P) ENTRE LOS TUBOS, EL TUBO (10) ES SIMETRICO AL TUBO (12). LA VELOCIDAD DEL FLUJO DE GAS A SER MEDIDO ES PREFERIBLEMENTE DEL ORDEN DE 0,3 A 10,00 M/S Y EL GAS ESTA A O SOBRE PRESION ATMOSFERICA.
