The density of blood isp =1.05-10° kg/m³. MOTION OF FLUIDS (part II)M TheoryConstantsn = 4- 10-3 Parsec is viscosity of blood;p= 1,05 - 10° kg/m blood density;g = 9,8 m/sec is free fall acceleration.hzFormulas1. Law of energy conservation for fluid:E = Ex + Ep + E, = const,Here Egfluid intemal energy.is fluid kinetic energy (m = pV); E, = mgh is fluid potential energy; E, = PV is2. Bernoulli's EquationThe relationship between pressure and velocity in fluids is described quantitatively by Bernoulli'sequation, named after its discoverer, the Swiss scientist Daniel Bemoulli (1700–1782). Bemoulli'sequation states that for an incompressible, frictionless fluid, the following sum is constant:+ pgh + P = const,where P is the absolute pressure, p is the fluid density, v is the velocity of the fluid, h is the heightabove some reference point, and g is the acceleration due to gravity. If we follow a small volume offluid along its path, various quantities in the sum may change, but the total remains constant. Let thesubscripts 1 and 2 refer to any two points along the path that the bit of fluid follows; Bernoulli'sequation becomes:Pri + pgh, + P, = i+ pghz + P..1.1 Bemoulli's Equation for static fluid, when v, = v2: pgh, + P, = pghz + P2PoAPPA R2P RPieg - Pneart = PgAhPheart - Phead = pgAhandPa1.2 Bemoulli's Equation at constant height h, = h2:pvž.-+ P =-+ P23. Laminar and turbulent flow, ReLaminar flow is characterized by the smooth flow of the fluid inlayers that do not mix. Turbulent flow, or turbulence, ischaracterized by eddies and swirls that mix layers of fluid together.An indicator called the Reynolds number Re can reveal whether flowis laminar or turbulent. For flow in a tube of uniform diameter, theReynolds number is defined as:LaminarTurbulentTransitional-oscillates betweenlaminar andturbulentpvdRe =Question
