This lesson focuses on the following Three Dimensional Learning aspects of NGSS:Ĭreate a computational model or simulation of a phenomenon, designed device, process, or system.Īlignment agreement: Thanks for your feedback! Use mathematical representations of phenomena to describe explanations.Īlignment agreement: Thanks for your feedback!Įnergy is a quantitative property of a system that depends on the motion and interactions of matter and radiation within that system. Use the Bernoulli equation to explain that faster airflow causes a decrease in pressure, and give an example of a real-life application.Ĭreate a computational model to calculate the change in the energy of one component in a system when the change in energy of the other component(s) and energy flows in and out of the system are known.Ĭlick to view other curriculum aligned to this Performance Expectation.Calculate an unknown fluid condition (for example, fluid pressure, velocity, density or height) at one point along a flow streamline, if conditions are known at another point along the same streamline.For example, in the case of a hydroelectric plant that utilizes water flow from mountain reservoir, knowing the elevation change from the reservoir in the mountains to the plant in town helps engineers determine how fast the water will be flowing through the energy-generating turbines in the plant.Īfter this lesson, students should be able to: The Bernoulli principle has a wide range of applications in engineering fluid dynamics, from aerospace wing design to designing pipes for hydroelectric plants. This engineering curriculum aligns to Next Generation Science Standards ( NGSS). Students use the associated activity to learn about the relationships between the components of the Bernoulli equation through real-life engineering examples and practice problems. Bernoulli's equation can be used to approximate these parameters in water, air or any fluid that has very low viscosity. Bernoulli's principle relates the pressure of a fluid to its elevation and its speed.
