<p> PIV expands its function from fluid velocity measurement to estimation of pressure, incorporating governing equations of flow. In this article, basic principle and applied algorithm of pressure field estimation from PIV data is explained. Since PIV has poor velocity resolution, use of differential equation encounters severe errors amplified. Several velocity-data filtering techniques are elaborated to overcome the error propagation in pressure field. As its applications, various type of pressure fields of a flow around a body are presented, including airfoil with surface jet, a Darrieus turbine blade, hydrofoil close to a free surface, and Savonius turbines.</p>
