Bernoulli's equation is a fundamental principle in fluid mechanics that relates the pressure, velocity, and height of a fluid at different points along a streamline. It states that the sum of the kinetic energy, potential energy, and pressure energy of a fluid is constant along a streamline.
Bernoulli's equation can be rearranged to calculate pressure differences between two points in a fluid flow. By equating the total energies at two points along a streamline, the difference in pressure can be found.
Bernoulli's equation is applicable to all fluids, both liquids and gases. However, it assumes that the fluid is incompressible and that there is no friction or viscosity present.
Bernoulli's equation has many practical applications, such as in the design of aircraft wings and propellers, the calculation of water flow in pipes and channels, and the operation of carburetors and atomizers.
While Bernoulli's equation is a useful tool, it does have some limitations. It assumes that the fluid is in steady flow, which may not always be the case. It also does not take into account factors such as turbulence and compressibility, which can affect the accuracy of the calculations.
