Continuity Equation

Mr. Anderson explains the continuity equation, an application of mass conservation in fluids. He discusses how changes in a fire hose's diameter affect fluid velocity, using the continuity equation A1V1 = A2V2. The video covers mass and volume flow rates, demonstrating with a PhET simulation. A practical problem is solved, showing how to calculate velocity changes when the nozzle size is altered. The video aims to help students understand and apply the continuity equation in fluid dynamics.
