Flow Rate and Viscosity Lab 
Flow Rate and Viscosity Lab Flow Rate Lab
Hypothesis:
If my group does this experiment correctly with no errors, then we should be able to get water as the fastest flow rate. Since water has the lowest viscosity, highest velocity and the lowest density when compared to the other materials being used in this lab water, ketchup, juice, syrup and sauce. Variables:
The fluid is being changed every time. Since we did this, we were able to compare the results and see the differences between these fluids. The size of the funnel, how fast the fluid was put in and how high the funnel was off the ground were all controlled variables. Analysis:
My hypothesis was correct because water was the fastest. In this experiment, my partner and I did everything correctly and to the best of our abilities. The only possible thing that we could have done wrong is with the timing. After comparing the flow rate with the amount of fluid stuck to the funnel, I have come to a conclusion that the in most cases, the faster the flow rate, the lesser the amount of fluid stuck to the funnel. Cohesion and adhesion are what cause some of the fluid to stay on the funnel. Certain liquids have different flow rates due to their viscosity. The higher the viscosity in a fluid, the lower the flow rate and vice versa. If this experiment wasn’t carefully controlled, then the result would be consisting of many errors. In this experiment, we controlled the height of the base of the funnel on a retort stand (20cm); the funnel size; how fast it was put in (poured the liquid in while a finger was put at the base of the funnel and started timer when finger was removed). The force of how one puts the fluid into the funnel can have a large impact on how fast the liquid moves through it. If the fluid is poured in with great amount of force, then the fluid will most likely go faster than it should. Funnel size is also
important because if the funnel is large,
