Abstract

SE PASA AIRE BAJO PRESION EN UNA TUBERIA 10 BAJO PRUEBA Y EN UNA CAMARA DE REFERENCIA 14 CONECTADA A LA TUBERIA 10 MEDIANTE UNA VALVULA 16 MIENTRAS SE REGISTRA EN INTERVALOS DE MUY POCOS SEGUNDOS LA TEMPERATURA EN LA CAMARA DE REFERENCIA 14, LA TEMPERATURA EN LA TUBERIA 10 Y LA PRESION ABSOLUTA EN LA CAMARA DE REFERENCIA 14. CUANDO SE HA ALCANZADO LA PRESION DE PRUEBA LA VALVULA SE CIERRA Y SE MIDE LA PRESION DIFERENCIAL ENTRE LA TUBERIA Y LA CAMARA DE REFERENCIA. LA VALVULA SE ABRE PARA IGUALAR LA PRESION Y A CONTINUACION SE CIERRA DE NUEVO Y SE MIDE LA VELOCIDAD DE MOVIMIENTO DE LA PRESION DIFERENCIAL. ESTO SE REPITE VARIAS VECES. SE UTILIZA UN ORDENADOR PARA CALCULAR UNA CURVA DE PREDICCION DE MOVIMIENTO LENTO. SE REALIZA UNA COMPARACION PARA VER SI LA VELOCIDAD DE MOVIMIENTO DE LA PRESION DEBIDA AL MOVIMIENTO LENTO Y AL ESCAPE SOLO EN LA TUBERIA INDEPENDIENTE DE CUALQUIER CAMBIO DE TEMPERATURA EN LA TUBERIA TIENDE A CRUZAR LA CURVA O NO.
