At the bifurcation of the femoral artery the pressure is 100 mm Hg. The venous pressure after either the left or right femoral artery is 10 mm Hg. The resistance in the right femoral artery is 1.67 times the resistance through the left femoral artery. The total flow rate just upstream of the bifurcation is 800 mL/min. How does the flow divide into the left and right femoral arteries

The values are $I_L = 500.37 \ mL / minutes$

and $I_r = 299.63 \ mL / minutes$

Explanation:

From the question we are told that

The pressure at the bifurcation of the femoral artery is $P = 100\ mm\ Hg$

The pressure at the left or right femoral artery is $P_r = P_l = 10 \ mm \ Hg$

The resistance in the left femoral artery is R_L

The resistance in the right femoral artery is R_r = 1.67 R_L

The total flow rate is I = 800 mL/minute

The diagram illustrating this question is shown on the first uploaded image

Generally this flow of blood through the artery can be compared to the a circuit as shown on the first uploaded image

Generally the rate at which blood flows through the left femoral artery is mathematically represented as

$I_L = I * \frac{R_r }{R_L + R_r}$

=> $I_L = 800 * \frac{1.67 R_L }{R_L + 1.67 R_L}$

=> $I_L = 800 * \frac{1.67 R_L }{2.67 R_L}$

=> $I_L = 500.37 \ mL / minutes$

Generally the rate at which blood flows through the right femoral artery is mathematically represented as

$I_r = I * \frac{R_L }{R_L + R_r}$

=> $I_r = 800 * \frac{R_L }{R_L + 1.67 R_L}$

=> $I_r = 800 * \frac{ R_L }{2.67 R_L}$

=> $I_r = 299.63 \ mL / minutes$

At the bifurcation of the femoral artery the pressure is 100 mm Hg. The venous pressure after either

Answer from: Quest

freezing

deposition

condensation

explanation;

melting also called fusion is the process where solid becomes liquid, sublimation is the process where solid becomes gaseous without first changing to liquid, deposition involves change from gaseous to solid state, freezing involves change from liquid to solid, boiling or evaporation involves change of liquid to gaseous state, while condensation is the change from gaseous state to liquid state.

endothermic reactions involves absorption of heat from the surroundings or the environment while exothermic reactions involves loss of heat energy to the surroundings.

in this case, sublimation, evaporation and melting are endothermic reactions (gain energy from the environment) while, freezing, deposition and condensation are exothermic (loss of energy to the surroundings) reactions.
