F = (P₁-P₂)/R where: F= rate of flow (ml min) P₁ = pressure at point 1 (mmHg) P₂= pressure at point 2 (mmHg) R = resistance to flow (mmHg min ml) This formula accounts for the effect of resistance (R), as well as the gradient of pressure (P₁-P₂). Resistance is the force that opposes the movement of blood through a vessel. Let's pause for a moment to make sure we fully understand the relationship between the resistance to blood flow, the gradient of pressure, and the rate of flow of blood. Directions: Use the formula for estimating blood flow (above) to help you answer questions 9-11. Set R to 1 mmHg min ml¹ for questions 9-11. Round all calculated values to the nearest one's place. For example, if you calculate the value as 3.821853, round to 4. 9. If the difference between P, - P₂ was 40 mmHg, what would the rate of blood flow (F) equal in ml min'?
