The SI unit of pressure is the pascal: 1 Pa = 1 N/m 2. Pressure due to the weight of a liquid of constant density is given by p = ρ ρ gh, where p is the pressure, h is the depth of the liquid, ρ ρ is the density of the liquid, and g is the acceleration due to gravity.

Dec 28, 2020 · Learn the key concepts and formulas of fluid dynamics, the study of moving fluids or fluid motion. Find out how to apply continuity, Bernoulli and laminar flow equations to various scenarios and applications.
Flux F through a surface, d S is the differential vector area element, n is the unit normal to the surface. Left: No flux passes in the surface, the maximum amount flows normal to the surface.
Describe the relationship between flow rate and velocity. Explain the consequences of the equation of continuity to the conservation of mass. The first part of this chapter dealt with fluid statics, the study of fluids at rest. The rest of this chapter deals with fluid dynamics, the study of fluids in motion.
P 1 P 2. This inverse relationship between the pressure and speed at a point in a fluid is called Bernoulli's principle. Bernoulli's principle: At points along a horizontal streamline, higher pressure regions have lower fluid speed and lower pressure regions have higher fluid speed.
