Under ideal laminar flow conditions, in which vascular resistance is independent of flow and pressure, the relationship between pressure, flow and resistance can be depicted as shown in the figure to the right because flow and resistance are reciprocally related, an increase in resistance decreases flow at any given p also, at any given flow along a blood vessel or across a heart valve, an
The water flow in your home is the maximum quantity of water you receive and this depends on the size of the pipe that connects between your home and your water service provider for example you will most probably get a satisfactory supply of water from a single tap connected to a small pipe
Thus, we have an inverse relationship between blood vessel resistance and the blood flow rate the higher the resistance, the slower the flow rate the relationship is expressed as follows now lets see if this makes any sense in numbers the usual pressure difference between the left and right ventricles is about mmhg
Pressureloss form in a cylindrical pipe of uniform diameter d, flowing full, the pressure loss due to viscous effects p is proportional to length l and can be characterized by the darcyweisbach equation , where the pressure loss per unit length p l si units pam is a function of , the density of the fluid kgm d, the hydraulic diameter of the pipe for a pipe
Sep , to calculate the new pump head pressure from an increase or decrease in flow rate, the following formula and calculation can be used calculate pump head pressure for an increase or decrease in flow rate to calculate the new pump head pressure from an increase or decrease in pump speed rpm, the following formula and calculation can be used
The relationship between the air flow rate cfm and the pressure of an air system is expressed as an increasing exponential function the graph below shows an example of a system curve this curve shows the relationship between the air flow rate and the pressure of an air system
Mar , pressure difference is the driving force for blood flow, and resistance is impediment to flow the relationship of flow q, resistance r, and pressure difference p is expressed by ohms law qpr the magnitude of blood flow is directly proportional to the pressure difference
Nozzle applications its almost always a pressure difference that causes flow a fluid will try to flow from high pressure to low pressure but there are other things that can cause flow, such as a height difference or even a temperature difference the basic relationship between flow and pressure for a nozzle is flowflow square root
