Vertical distance

In preparation for a field wide quick look correlation, all well logs need to be corrected for borehole inclination. This is done routinely with software which uses the measured depth below the derrick floor ( alonghole depth below derrick floor AHBDFor measured depth , MD) and the acquired directional surveys to calculate the true vertical depth subsea (TVSS). This is the vertical distance of a point below a common reference level, for instance chart datum (CD) or mean sea level (MSL). Figure 5.41 shows the relationship between the different depth measurements. 

Figure 9-5. Linear regression The sum of the squares of the vertical distances of the points from the line is minimized.

The goal of linear regression is to adapt the values of the slope and of the intercept so that the line gives the best prediction of y from x. This is achieved by minimizing the sum of the squares of the vertical distances of the points from the line. An example of linear regression is given in Figure 9-S. 

Figure 3.10 is a plot of potential against distance from the wall for a liquid in a capillary of sufficient width for its middle A to be outside the range of forces from the wall. Since the capillary condensate is in equilibrium with the vapour, its chemical potential (=p represented by the horizontal line GF, will be lower than that of the free liquid the difference in chemical potential of the condensate at A, represented by the vertical distance AF, is brought about entirely by the pressure drop, Ap = 2y/r , across the meniscus (cf. Equation (3.6)) but at some point B. say, nearer the wall, the chemical potential receives a contribution represented by the line BC, from the adsorption potential. Consequently, the reduction Ap in pressure across the meniscus must be less at B than at A, so that again... 

Rotameter A rotameter consists of a vertical tube with a tapered bore in which a float changes position with the flow rate through the tube. For a given flow rate the float remains stationary since the vertical forces of differential pressure, gravity, viscosity, and buoyancy are balanced. The float position is the output of the meter and can be made essentially linear with flow rate by makiug the tube areavaiy hn-early with the vertical distance. 

Static Suction Head The static suction head / is the vertical distance measured from the free surface of the hquid source to the pump centerhne plus the absolute pressure at the liquid surface. 

Velocity Head This is the vertical distance by which a body must faU to acquire the velocity v. 

One of the most important material-handling techniques in the chemical industry is the movement of material suspended in a stream of air over horizontal and vertical distances ranging from a few to several hundred feet. Materials ranging from fine powders through 6.35-mm (lA-in) pellets and bulk densities of 16 to more than 3200 kg/m (1 to more than 200 Ib/ft ) can be handled. A large, capable manufacturing... 

The discharge head is the vertical distance from the centerline of the pump (this would be the shaft on a horizontal pump) to the level in the discharge vessel. 

H = Vertical distance (center to center) between Ai and A2, ft. This was weight averaged for various w indows and open doors. 

Next, a global representation of all process lean streams is developed as a lean composite stream. First, we establish Ns/> lean composition scales (one for each process MSA) that are in one-to-one coirespondence with the rich scale according to the method outlined in Section 3.5. Next, the mass of pollutant that can be gained by each process MSA is plotted vei us the composition scale of that MSA. Hence, each i xx ess MSA is represented as an arrow extending between supply and target compositions (see Fig. 3.5 for a two-MSA example). Ihe vertical distance between the arrow head and tail is given by... 

Thus the vertical distances to be used in the plume characteristics calculation are correspondingly equal to 2.31 m and 4.31 m. 

Drop of jet The vertical distance between the lowest horizontal plane tangent to a specified isovel and the center of the core of an air jet. 

The temperature of the inner pipe fluid in either case varies according to one curve as it proceeds along the length of the pipe, and the tempera ture of the annular fluid varies according to another. The temperature difference at any point is the vertical distance between the two curves. 

To make contact with the SEA experiment one has to realize that the confining surfaces are only locally parallel. Because of the macroscopic curvature of the substrate surfaces, Tzz becomes a local quantity which varies with the vertical distance Sz = Sz x,y) between the substrate surfaces (see Fig. 2). Since the sphere-plane arrangement (see Sec. II Al) is immersed in bulk fluid at pressure Pbuik the total force exerted on the sphere by the film in... 

Let us apply this method to the hypothetical reaction coordinate diagram of Fig. 5-11, which consists of two sections. The requisite energy differences are for the vertical distances (T2 — R) and (T3 — I2). Because (T3 — I2) > (T2 — R), the second section contains the rds, which must be the I2 —> T3 step. Note that T3 actually has a lower free energy than do Ti and T2 it is the change in free energy from the valley at the beginning of the section that determines the rate. 

A plot of log (kiku) against pKa (this is called a Br nsted-type plot, as we will see in Section 7.4) for meta- and para-substituted pyridines gave an LFER describing normal behavior. On this same plot the or// o-substituted pyridines all fell below the m and p reference line. The steric constant was defined as the vertical distance between the reference line [whose equation was log (k plkn) = 0.35 pK — 1.73] and the result for the ortho compound, or... 

In its development, it adapted two existing technologies, In the agricultural sector, the mechanics of grain elevators provided a model for how to move solids vertical distances and in closed-loop flow arrangements. Sacony engineers modified the elevator bucket systems traditionally used by the grain industry to carry hot catalyst from the bottom to top of vessels and between vessels.
