What is the reynolds number for blood leaving the heart through the aorta if the diameter of the aorta is 2.15 cm and the blood has a dynamic viscosity of 2.70 × 10-3 pa·s, a density of 1050 kg/m3, and travels at a mean fluid velocity of 28.9 cm/s?

Reynolds number will be 2416.3611

Explanation:

We have given diameter of aorta d = 2.15 cm = 0.0215m

Dynamic viscosity of blood

Fluid velocity

Fluid density

We have to find the Reynolds number

We know that  Reynolds number is given by

emily ruth's annual premium is $1058.50

step-by-step explanation:

emily ruth is a female of 27 years age purchasing 20 year endowment insurance with face value $25000.

from the given table,

for females, the age of a male 3 years younger should be used.

so, we have to check for 24 year male for 20 year endowment.

it is 42.34 for every $1000 face value.

for a face value of $25000,

it is 25 * 42.34 = $1058.50

∴ emily ruth's annual premium is $1058.50
