Usando el viscosmetro Fann 35A se caracterizaron reolgicamente tres fluidos a la temperatura de laboratorio (80 F): Miel de Maple, un aceite lubricante y un lodo. Los resultados se muestran en la tabla. Para cada fluido determine: Los resultados se muestran en la tabla. Para cada fluido construya reogramas y determine: 1. Si es un fluido Newtoniano o no.2. Cual es el modelo matemtico que mejor representa su comportamiento.3. Los parmetros del modelo matemtico.4. Usando los parmetros anteriores, para cada fluido calcule la viscosidad (en cP) a una ratas de corte a 1, 5, 10, 50, 100, 200, 300, 400, 500 y 600 S-1. Grafique la viscosidad calculada en funcin de la rata de corte y analice su variacin.
