While looking for parameters that may affect the experiment results, one of the basic experimental principles can be adopted: the principle of controlling a single variable. This experiment is centered on the flow rate of the liquid in the plastic bottle, and the fixed value that remains unchanged is the physical properties of the bottle itself and the liquid. The density of the liquid and the angle of the bottle are two factors that could affect the flow-out rate. The ten different angles from 0° to 90° are chosen to be observed. And five different densities of alcohol are chosen to be tested as well. Under reasonable error control, the angle of the bottle body can be obtained when the liquid flow rate is the maximum. Based on the experimental derivation process recorded in this article, the basic knowledge of statistics is used, combining with as much precision measuring equipment as possible. Then, the Bernoulli equation is also used to calculate the ideal value, which is also compared with the actual value, to get the impact factors. The experimental results are scientifically analysed and deduced, and finally, substantial results are obtained.
