Describe the graph of flow versus viscosity Rating: 9,7/10 577 reviews

The graph of flow versus viscosity is a representation of the relationship between two properties of a fluid: its ability to flow and its resistance to flow. In general, the viscosity of a fluid is a measure of its thickness or resistance to flow, while flow is a measure of the ease with which a fluid can move through a system.

When plotted on a graph, the flow of a fluid is typically represented on the x-axis, while the viscosity of the fluid is plotted on the y-axis. The resulting graph can take on a variety of shapes, depending on the specific properties of the fluid being plotted.

One common type of graph of flow versus viscosity is a linear graph, in which the slope of the line represents the fluid's viscosity. In this type of graph, a fluid with a high viscosity will have a steeper slope, while a fluid with a low viscosity will have a shallower slope.

Another type of graph of flow versus viscosity is a non-linear graph, in which the relationship between flow and viscosity is not a straight line. This type of graph is often seen in fluids that exhibit non-Newtonian behavior, such as fluids that are shear-thinning or shear-thickening. Shear-thinning fluids, such as ketchup or paint, become less viscous when subjected to shear stress, while shear-thickening fluids, such as toothpaste or non-Newtonian mud, become more viscous under the same conditions.

In addition to these two common types of graphs, there are also other shapes that may be seen on a graph of flow versus viscosity. For example, a fluid with a constant viscosity over a range of flows may produce a horizontal line on the graph, while a fluid with a viscosity that increases rapidly at low flows and then levels off may produce a curve on the graph.

Overall, the shape of the graph of flow versus viscosity is a useful tool for understanding the behavior of fluids and predicting how they will behave under different conditions. It can be used to compare the properties of different fluids, to design systems that involve the flow of fluids, and to understand the behavior of fluids in various applications.

## Flow vs Pressure: Why, When, Detailed Facts

The data is just telling you what the plastic wants to do; all the other components of making a good part have to be considered by testing. Pressure: Pressure can be expressed s atmospheric pressure. If it is weak, systolic pressure has fallen, and medical intervention may be warranted. Activity 6 Questions: 1. Pulsatile laminar flow 3. Radius change is directly proportional on laminar flow.

Which mechanism had the greatest compensatory effect? Fluid Flow What is Fluid Flow? Pressure graph: The pressure graph actually looks like a hyperbola. In this process, the heart is stretched which results in a more forceful contraction of the ventricles. This causes blood to flow along its pressure gradient from veins outside the thorax, where pressure is higher, into the thoracic region, where pressure is now lower. Pressure trigger: In the mechanical ventilation, the flow trigger is designed as that process where the airway pressure would be decreases thus the pressure trigger is appear. Fluid Flow is a part of fluid mechanics and deals with fluid dynamics. Alternatively, plaque can break off and travel through the bloodstream as an embolus until it blocks a more distant, smaller artery. Both the rate and the strength of the pulse are important clinically.

This may seem surprising, given that capillaries have a smaller size. Low blood volume, called hypovolemia, may be caused by bleeding, dehydration, vomiting, severe burns, or some medications used to treat hypertension. The systolic pressure is the higher value typically around 120 mm Hg and reflects the arterial pressure resulting from the ejection of blood during ventricular contraction, or systole. Through the process of vasodilation, or the smoothing of the blood vessel muscle, you can change the radius of the vessel more frequently. As referenced from this experiment, weight, either gain or loss effects blood vessel length.

Discuss the effect that. How well did the results compare with your prediction? Flow vs pressure trigger: The term triggering is attached with the other physical quantities, they are respectively, motion, pressure, impedance, flow and volume. Compliance Compliance is the ability of any compartment to expand to accommodate increased content. Hypervolemia, excessive fluid volume, may be caused by retention of water and sodium, as seen in patients with heart failure, liver cirrhosis, some forms of kidney disease, hyperaldosteronism, and some glucocorticoid steroid treatments. Yet, when stroke volume increases, the heart rate must decrease to maintain cardiac output.

Then the value of the pressure which we get from the experiments should be pointed in the graph. As viscosity increase flow decrease. I would estimate that 80% of all molding jobs should not need profiling. You experience more resistance and therefore less flow from the milkshake. The vascular tone of the vessel is the contractile state of the smooth muscle and the primary determinant of diameter, and thus of resistance and flow.

## Understanding Polymer Flow: Interpreting the Viscosity Curve

The influence of lumen diameter on resistance is dramatic: A slight increase or decrease in diameter causes a dramatic decrease or increase in resistance. In the blood flow equation as seen to the right , blood flow is directly proportional to the fourth power of vessel radius. Pulse, the expansion and recoiling of an artery, reflects the heartbeat. The calculator below is for informative purposes only. As noted earlier, hydrostatic pressure is the force exerted by a fluid due to gravitational pull, usually against the wall of the container in which it is located. These factors include parasympathetic stimulation, elevated or decreased potassium ion levels, decreased calcium levels, anoxia, and acidosis. Alternatively, plaque can break off and travel through the bloodstream as an embolus until it blocks a more distant, smaller artery.

## Fluid Flow

When vascular disease causes stiffening of arteries, compliance is reduced and resistance to blood flow is increased. The same equation also applies to engineering studies of the flow of fluids. Explain the effect that pressure changes had on flow rate. The graphic curve will be updated as well. The graph of flow versus viscosity are inverse proportional. As blood flows through the veins, the rate of velocity increases, as blood is returned to the heart. You can find the equation on Google.

## Blood Flow, Blood Pressure, and Resistance

Venous return to the heart is reduced, a condition that in turn reduces cardiac output and therefore oxygenation of tissues throughout the body. A little caveat here: If it is a multi-cavity tool, fill balance is important. Treatment includes lifestyle changes, such as weight loss, smoking cessation, regular exercise, and an adoption of a diet low in sodium and saturated fats. Activity 2 Questions: 1. The important thing to remember is this: Two of these variables, viscosity and vessel length, will change slowly in the body. Viscosity is the resistance to flow so higher viscosity fluids flow more slowly at a given level of force pushing them along. An increase in blood viscosity directly affects blood flow, in that blood flow would decrease.

Flow tube radius change has a direct effect on flow rate. Further, the distribution of vessels is not the same in all tissues. The pulse is most readily measured at the radial artery, but can be measured at any of the pulse points shown. Describe how the heart alters stroke volume? In an open system by the process the mass of the liquid substance is move one area to another area in a fixed time at a standard pressure. Any factor that causes cardiac output to increase, by elevating heart rate or stroke volume or both, will elevate blood pressure and promote blood flow.

Arteriosclerosis begins with injury to the endothelium of an artery, which may be caused by irritation from high blood glucose, infection, tobacco use, excessive blood lipids, and other factors. In contrast, a high or wide pulse pressure is common in healthy people following strenuous exercise, when their resting pulse pressure of 30—40 mmHg may increase temporarily to 100 mmHg as stroke volume increases. Overall, vessels decrease in length only during loss of mass or amputation. It normally approaches zero, except when the atria contract. Micrograph provided by the Regents of University of Michigan Medical School © 2012 Sometimes a plaque can rupture, causing microscopic tears in the artery wall that allow blood to leak into the tissue on the other side.
