Below are typical values for blood flow through a coronary artery. Note that viscosity of the blood is not neglected. Density of blood, ρ = 1060 kg/m3 Viscosity of blood, ν = 0.004 Pa x s Flow rate, Q = 0.8 mL/s Length of artery, L = 3.5 cm Radius of artery, r = 0.2 cm For the same pressure drop, calculate the flow rate if the radius of the artery reduces by 30% its original value due to blockage?

3. A Newtonian fluid with a dynamic or absolute viscosity of 0.38 Ns/m” and a Density of 910 kg/m flows through a 25 mm diameter pipe with a velocity of 2.6 m/s. Find out Reynolds number of the fluid. Is the fluid flow lamina, transient, or turbulent?
Calculate the Reynolds number, Re = (2rρv)/ η , for the following situations and decide whether the flow of fluid around them is laminar or turbulent. Then calculate the frag force using the appropriate formula. For the radius, use r = 2(Area/perimeter) which, for a circle, gives the radius. Densities and viscosities are in the table on page 2. Also, to keep things uniform, we will use the boundaries for laminar and turbulent flow from Engineer's Toolbox, also on pg....

The sulphuric acid has a viscosity of 25 mN.s/m2 and density of 1680 kg/m3 while the roughness of the pipe surface is 1.3 mm. If the operating temperature is 290K, determine fluid flow (examples turbulent, laminar or others).
Calculate the Reynolds number, Re- (2rpv)/ n, for the following situations and decide whether the flow of fluid around them is laminar or turbulent. Then calculate the frag force using the appropriate formula. For the radius, use r 2(Area/perimeter) which, for a circle, gives the radius. Densities and viscosities are in the table on page 2.

The Reynolds Number, Re, is of great importance in Chemical Engineering. This dimensionless quantity is used to describe fluid flow patterns. If Re is over 2,100 the flow regime is considered turbulent and below 2,100 the flow regime is laminar. Re is defined as the ratio of inertial forces to viscous forces. And is represented mathematically as: ?? = ??? ? , where D is the pipe diameter (length), u is the fluid velocity (length/time), ? is the fluid density...
Sulphuric acid is flowing through a pipe (2.5 inch diameter, 50 ft length) in a velocity of 0.006 m3 /s. The sulphuric acid has a viscosity of 25 mN.s/m2 and density of 1680 kg/m3 while the roughness of the pipe surface is 1.3 mm. If the operating temperature is 290K, determine fluid flow (i.e. laminar, turbulent or others). (Given that 1 m = 39.37 inch).
