Pull-down

The above examples are shown for water coning and cusping. The same phenomena may be observed with overlying gas being pulled down into the producing oil well. This would be called gas coning or cusping. 

If the plates pull down, they would sink into the mantle and melt to form ocean basins. Some of the molten rock of these plates may travel to the earth s surface through the crevice so formed due to heat convection and cause a volcano.

If a plant has been shut down long enough for all pressures to equalize and is then restarted, the suction pressure will pull down below normal until the liquid refrigerant has begun to circulate. Under such circumstances the low-pressure switch may operate. This is a normal occurrence, but may require the addition of a delay timer to prevent frequent starting of the compressor motor. 

Special instructions for specific ear preparations are found in the Summary Drug Table Otic Preparations. When instilling ear drops, the nurse has die patient lie on his or her side with the ear toward the ceiling. If the patient wishes to remain in an upright position, the head is tilted toward the untreated side with the ear toward the ceiling (Fig. 57-1). hi the adult, the earlobe is pulled up and back. In children, the earlobe is pulled down and back. The nurse instills die prescribed number of drops into the ear canal. If die primary health... 

We want to find the relation between the height, h, of the column of mercury in a barometer and the atmospheric pressure, P. Suppose the cross-sectional area of the column is A. The volume of mercury in the column is the height of the cylinder times this area, V = bA. The mass, ttt, of this volume of mercury is the product of mercury s density, d, and the volume so m = dV = dhA. The mercury is pulled down by the force of gravity and the total force that its mass exerts at its base is the product of the mass and the acceleration of free fall (the acceleration due to gravity), g F = mg. Therefore, the pressure at the base of the column, the force divided by the area, is... 

Menu Bar, Pull-Down Windows The first item in the menu bar is the pulldown menu (File), which lists the appropriate selections (Open File), (Close File), and (Close LinReg). 

Across the top there is a menu bar with the usual Windows-type pull-down menus arranged from left to right in the order Files, Data Selection, Data Manipulation, Extras/Options, Output, or similar. Those options that are allowed or make sense in a given context are activated. Requests for numerical input make use of the standard Windows-type gray box with the question that is to be answered, the white area into which the data is written, and the appropriate confirmatory Yes/No/Cancel buttons. 

In the case of the capillary blood, it is extremely important that the specimen not be allowed to stand for extensive periods of time before centrifugation. If the blood is to be transferred to the pH meter, then the collecting tube is sealed at both ends during transportation. It is then aspirated into the pH instrument as soon as practicable since one needs a smooth even flow in order to aspirate a specimen into the conventional micro pH meter. After the whole blood has been sampled for various purposes, it is important that the remaining blood be centrifuged promptly. If not, it will clot. Subse-quentially, centrifuging with a clot will tend to hemolyze the blood. Erythrocytes will adhere to the wall and as they are pulled down by the clot, they will be ruptured. Those who do not observe these precautions will find that it is rather difficult to obtain unhemolyzed blood.

A blank LTI window will pop up. The first task would be to poke into features supported under the File and Tools pull-down menus and see what we can achieve via point-and-click. There is also a Help pull-down menu, which activates the Help Window. 

Now, go to the LTI Viewer window and select Import under the File pull-down menu. A dialog box will pop out to help import the transfer function objects. By default, a unit step response will be generated. Click on the axis with the right mouse button to retrieve a popup menu that will provide options for other plot types, for toggling the object to be plotted, and other features. With a step response plot, the Characteristics feature of the pop-up menu can identify the peak time, rise time, and settling time of an underdamped response. 

All we need is to drag-and-drop the icons that we need from the toolboxes into a blank model window. If this window is not there, open a new one with the File pull-down menu. From here on, putting a feedback loop together to do a simulation is largely a point-and-click activity. An example of what Simulink can generate is shown in Fig. M5.3. 

Before we start a simulation, choose Parameters under the Simulation pull-down menu to select the time of simulation. If we are using the XY Graph, we need to double-click its icon and edit its parameters to make the time information consistent. 

For curious minds The first time you use the PID controllers, drag the icon onto a new simulation window, select the icon and then Look under mask under the Edit pull-down menu. You will see how the controllers are put together. The simple PID controller is... 

A graphics window with pull-down menus and tool buttons will pop out. Here are some pointers on the usage of the tool. 

Similar to the LTI Viewer, the root locus tool runs in its own functional space. We have to import the transfer functions under the File pull-down menu. 

The default is a proportional controller, but the K block in Fig. M6.1 can easily be changed to become a PI, PD, or PID controller. The change can be accomplished in different ways. One is to retrieve the compensator-editing window by clicking on the K block or by using the Tools pull-down menu. The other is to use the set of arrow tools in the root locus window to add or move open-loop poles and zeros associated with the compensator.
