Be sure to include the point (W/,) = (0,0) to verify that the t is reasonable. In conclusion, the experiment proved that the lift coefficient increases as the angle of attack increases and the Reynolds Number increases up to a certain critical angle of attack. Viscosity describes the internal resistance to flow of a fluid (internal friction). Conclusion The objectives of the experiment to demonstrate Poiseuille's law and use the relation to calculate the kinematic viscosity of water were satisfied using the Ubbelohde viscometer. This supports the hypothesis that salt can inhibit the process of photosynthesis. Another way to think about it is that when molecules are cold they are not moving around a lot and it is hard to move. Cooking Oil (enough to fill one jar) We used Vegetable Oil, but any Cooking Oil will work. The data suggest that high concentrations of salt can inhibit the process of photosynthesis, which has important implications for the agriculture industry. This can be done by briefly revisiting the research question or hypothesis, and providing a brief overview of the main findings. Practical investigation into Viscosity in liquids (Stokes Law). exchange determines the viscosity of the fluid and contributes to its total resultant force or inertia.
