When a fluid is in motion, it must move in such a way that mass is conserved. To see how mass conservation places restrictions on the velocity field, consider the steady flow of fluid through a duct ...

points 1 and 2 lie on a streamline, the fluid has constant density, the flow is steady, and there is no friction. Although these restrictions sound severe, the Bernoulli equation is very useful, ...

ventricular function and vascular flow. A free-breathing, dual-phase respiratory-gated and ECG-triggered 3D steady-state free precision (SSFP) scan of the heart and great vessels and 3D contrast ...
