Bernoulli's Principle
We set out to find if Bernoulli's equation, which is still used by engineers today, can actually work, even in a simple test. This equation is derived through Bernoulli's Principle, which is used to find out why an airplane is able to fly and calculate certain pressures within fluid flowing systems. This principle states that if the speed of a fluid particle increases as it travels along a horizontal streamline, the pressure of the fluid must decrease, and conversely. The simple experiment that we designed to test Bernoulli's Principle involved two pipes of different diameters, at different heights, through which water flowed. Velocity and pressure measurements were taken at different locations. Particles were inserted into the fluid and their velocities were measured to determine fluid velocity, and a pressure gauge was tapped off the pipe, used to measure the fluid pressure. This data, velocities and pressures, were then inserted into Bernoulli's Equation to help determine whether or not this equation can be confirmed from this simple experiment. The data resulted in a small amount of error and we were able to gain information as to if the equation can truly work or not. The data was collected carefully and we are confident to conclude the Bernoulli Principle to be true.
