2) Determinar el tipo de flujo que tendr lugar en una tubera de 12pulg de dimetro. Si:

El flujo en movimiento es agua a 60 f con una velocidad de 3.8 ft/s.

El fluido es acido sulfrico ()de 98 %en peso a la temperatura de 60 f, de viscosidad igual a 0.02899lb/ft-s y una densidad de 114 lb/ft a la velocidad anterior

Resolucin

Planteamiento.

Si Re4000 flujo turbulento

Re =

10) En una planta industrial se bombea 35tm/H de acido sulfrico () de densidad relativa de 1.75. el motor de la bomba que la impulsa tiene una potencia de 1.8HP adems sabemos que el rendimiento de la bomba es del 80%, si para vencer la friccin se requiere de 2.5lb/ft . Determinar la diferencia de nivel, es decir la altura a la que se eleva el acido.
