WebSBP = Systolic Blood Pressure DBP = Diastolic Blood Pressure Thigh/Arm Circumference = Measured in Centimeters. For example, if the subject is a healthy male with Blood Pressure of 120/80 and thigh circumference of 52 centimeters the lower body equation would look like the following: = 0.912 (120) + .734 (80) + 5.893 (52) - 220.046 WebResistance is how hard the vessel is trying to stop the flow of fluid. It's made up of how small the vessel is, and the friction along the sides. Flow is the amount of fluid that's passing through the vessel over an amount of time. It's determined by how much the pressure can push against the resistance. ( 4 votes)

WebThe basic form of Poiseuille’s law and its primary equation are simple, as shown below: In this equation, u is the volumetric flow rate of the fluid. This law shows that the volumetric flow rate of a viscous fluid through an enclosed pipe is proportional to the 4th power of the pipe’s dimension in the cross section (the radius or diameter ... WebJan 1, 2024 · Poiseuille Law Formula. Q = π⋅r⁴⋅P / 8⋅η⋅l. Q is flow rate. Flow is measured in volume over time or m3s. Note: Flow rate isn’t the same as linear speed or flow velocity, seen in Q=AV. Q is the flow rate, but v is the linear velocity of the flow you’re looking at. Make sure not to mix up Q and V. r is the radius of the closed pipe.

WebThe left end of the tube is at a high pressure and the right end is at a lower pressure (consider the fluid moving from left to right). According to continuity, Φ 1 = flow rate 1 = Φ 2 = flow rate 2. or. A 1 v 1 = A 2 v 2. where A and v are the cross sectional area and velocity respectively. Now consider the a disease/condition where the ... WebThe total blood flow in series, Q, is equal across all parts of the system.
