Abstract:
AbstractWe investigate the dynamics of an object towed over the surface of an initially flat, deformable layer. Using a combination of simple laboratory experiments and a theoretical model, we demonstrate that an inclined plate, pivoted so as to move up and down, may be towed steadily over a substrate at low speed, but become unstable to vertical oscillations above a threshold speed. That threshold depends upon the weight of the plate and the physical properties of the substrate, but arises whether the substrate is a viscous fluid, a viscoplastic fluid, or a granular medium.

Abstract:
This chapter covers an important step toward our development of dynamical equations of fluid motion. Herein we will develop explicit expressions for the forces that produce the fluid accelerations that we described kinematically in Chapter 7. In particular, we will consider the behavior of inviscid fluids. Viscous forces therefore are not involved; accelerations are wholly due to body forces and normal surface forces associated with fluid pressure. The results of our development are Euler’s equations, or the momentum equations for inviscid flow. One consequence of the inviscid assumption is that slip flow may occur at real boundaries, in contrast to the no-slip condition that occurs with real fluids. This is unrealistic for the viscous flows of interest in many geological problems. Nonetheless, situations exist in which viscous fluids can be treated as inviscid. Examples include fluids having small viscosity, and flows far from boundaries. The study of inviscid flow therefore is justified in its own right. A particularly important example involves the consideration of how velocity and pressure vary along a streamline, which leads to Bernoulli’s equation. Consider a rectangular control volume with edges of length dx, dy, and dz embedded within a local Cartesian coordinate system. This local system has an arbitrary orientation with respect to the Earth coordinate system; the x-axis is inclined at an angle α measured from the horizontal. Acceleration due to gravity g acts vertically, and the centroid of the control volume is at height h above a horizontal datum. The height h provides a measure of the position of the fluid within the gravitational field. Consider, now, forces acting on the control volume parallel to the x-axis. The weight W of fluid within the control volume possesses a component Wx parallel to the x-axis: . . . Wx = −ρg sin α dx dy dz . . . . . . (10.2) . . . where ρ is the fluid density, and the negative sign indicates that Wx acts in the direction of negative x.

Abstract:
If you're going to understand how to think about pressures within the circulatory system, though, you'll need to know a few of the not-so-obvious principles of hydrostatics. Hydrostatic pressure is affected only by the density of the fluid, its vertical height above or below a measurement point, and the acceleration due to gravity. If the larger mass of water in the ocean exerts greater pressure than the smaller mass of water in your vertical pipe, then you should see water perpetually flowing through the pipe and rising higher than sea level. Continual flow doesn't happen in this example for the same reason as described above—hydrostatic pressure is not determined by the shape of the fluid container or the total mass of fluid that it contains. Here, only the vertical distance above the measurement point is important. Now let's apply these principles to the siphon, defined as any fluid-filled conduit that excludes air. The reason for broaching this issue is that the cardiovascular system also obeys the principle of the siphon.

Abstract:
Many infusions are given by gravity assisted, drip sets that give a flowrate dependent on the height of the reservoir above the patient, the length of the tubing, the bore of the IV cannula, the density and viscosity of the fluid being delivered, and the patient’s venous pressure. However there is an increasing tendency to use programmable volumetric intravenous pumps and syringe drivers to deliver intravenous anaesthesia, fluids, patient controlled analgesia, epidural infusions and other drugs. Not only are they programmable, but they can also be adjusted to give desired flowrates or volumes. Some infusion devices are powered only by gravity, but the flowrate is controlled by a photoelectric drip rate detector in conjunction with a microprocessor controlled drip occlusion device. Other infusion devices use a stepper motor to control the rate of infusion. A stepper motor is designed so that the rotation is by a fixed amount per supplied electrical pulse, independent of the mechanical load it is carrying. The pulses are controlled by a microprocessor in the pump and the rate of infusion is dependent on the stepper motor’s output. Syringe drivers are designed to use a range of syringe sizes and some require special delivery tubing. The flow is a continuous, pulsatile flow and accuracy is 2–5%. Some syringe drivers are driven by clockwork motors, others by a battery powered motor that is intermittently on and off, depending on required flowrate. The driving mechanism is usually by a screw threaded rod connected to the syringe plunger. Other syringe drivers use a stepper motor connected to the screw threaded rod. Care should be taken not to position the syringe driver above the patient’s venous cannula or the syringe may siphon a drug additional to that programmed on the driver, by virtue of the weight of the column of fluid in the tubing above the patient. Care should also be taken to avoid any bubbles in the syringe reaching the patient. Modern syringe drivers are usually sufficiently accurate over the desired range of infusion [Stokes et al. 1990]. However, there may be a delay before the drug is delivered to the patient as the parts attached to the syringe take up slack [O’Kelly et al. 1992].

Full text
Abstract:
The objective of barometry is to measure the static pressure exerted by the atmosphere. Static pressure is the force per unit area that would be exerted against any surface in the absence of air motion. It is an isotropic, scalar quantity. Dynamic pressure is the force per unit area due to air motion. It is a vector quantity, following the wind vector. This chapter is concerned with determining the static air pressure and doing so in the presence of air motion (wind) that requires special measurement techniques. The Earth’s atmosphere exerts a pressure on the surface of the Earth equal to the weight of a vertical column of air of unit cross-section. Since air is a fluid, this pressure, or force, is exerted equally in all directions. The static pressure at the surface is given by where g(z) = acceleration due to gravity at height z above sea level in ms-2, and ρ = density as a function of height, kg-3. The SI unit of pressure is the pascal, abbreviated as Pa. In meteorology, the preferred unit of pressure is the mb or the hPa (equivalent magnitude). Table 2-1 lists some conversion factors for units currently in use in pressure measurement and also for some units no longer favored. Standard sea level pressure in various units is shown in table 2-2. The last line of table 2-2 refers to the units of Ibf in-2,also called psi (pounds per square inch). Pressure measurements are often called absolute (psia), gauge (psig), or differential (psid). Absolute pressure is simply the total static pressure exerted by the gas (or fluid) and so the barometric pressure is also the absolute pressure. Gauge pressure is the pressure relative to ambient atmospheric pressure. Pressure in an automobile tire is measured relative to atmospheric pressure so it is gauge pressure, not absolute pressure. Differential pressure is the pressure relative to some other pressure. Gauge pressure is a special case of differential pressure. In addition to the static pressure there is a dynamic pressure exerted by wind flow.

The development and testing of two novel micropumps called the single-disk and double-disk viscous pumps are described. A single disk and the top pump housing, or two disks are separated by a small gap that forms a fluid passage. A wiper, that is the height of this gap, is placed between the two disks, or between the single disk and top pump housing, and extends from the outer diameter of the disk(s) to the center region of the disk(s). The movement of the disk(s) induces viscous stresses on the fluid that forces the fluid through the pump area above the single disk, or between the two disks.
