👉 A principle fluid, also known as an ideal fluid, is a theoretical concept in fluid mechanics that simplifies the behavior of real fluids by ignoring viscosity and surface tension. This means it assumes fluids flow smoothly without internal friction or energy loss due to surface interactions, making calculations more straightforward. While real fluids exhibit these properties, ideal fluids serve as a useful approximation for many practical applications, especially in engineering and theoretical studies, where the complexity of viscosity and surface tension can be significant. By focusing on these idealized characteristics, engineers and scientists can more easily model and predict fluid behavior in various scenarios.
