olganol [36]3 years ago
7 0

Answer:

Each time your heart beats, an electrical signal travels through the heart. An EKG can show if your heart is beating at a normal rate and strength. It also helps show the size and position of your heart's chambers. An abnormal EKG can be a sign of heart disease or damage.

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
defon

Answer:

b. laminar flow

the reynold number is 1329.26

Explanation:

Re = (V x D x ρ)/ η

where,

V = mean velocity = 15.9 cm/s = 0.159m/s

D = vessel diameter = 2.15cm = 0.0215m

ρ = blood density = 1050 kg/m3 = 0.00105 kg/cm3

η = dynamic viscousity= 2.70 × 10-3 Pa·s = 2.70 × 10-3 kg/m-s

applying the formular to calculate for reynolds number, Re =

Re = (V x D x ρ)/ η

   =(0.159 x 0.0215 x 1050) / 2.70 × 10-3

   =3.589/0.0027 = 1329.26

the Reynolds number for the 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 15.9 cm/s is 1329.26

which flow through the aorta in a Laminar flow

Note that

a) turbulen= Re  >4000

b) laminar= Re  <2300

c) transitioning between laminar and turbulen= Re between 2100 and 4000

Although scientific theories are based on strong evidence, they can change over time. Which of the following correctly explains
Ray Of Light [21]

Answer:

Scientists argue, re-examine, and consider new explanations to new data

Explanation:

Theories are susceptible to changes and new data can be incorporated into the theory because advances and discoveries are made.Scientific theories are testable and make falsifiable predictions thus, scientists argue, re-examine, and consider new explanations to new data.As additional scientific evidence is gathered, a new scientific theory may be modified and ultimately rejected if it cannot be made to fit the new findings.

Although theories are only modified in most cases, when a theory lacks any of the following characteristic they are susceptible to rejection by the scientists. A theory must be observable and repeatable to avoid frauds. Theories should be testeable and make falsifiable predictions with consistent accuracy across a broad area of scientific inquiry. It should also be well-supported by many independent strands of evidence. In addition, having consistency with preexisting experimental results and accuracy in its predictions as in any preexisting theories. All the above features provide room for change in theories over-time.
