Foot-Moving

Sally nods. Using your formula, this means that no matter in what direction you move eight feet away from my finger, the additional fifteen-foot move upsilon gives a point exactly seventeen feet away from my fingertip. ... 

Take-Up and Hold-Back. An elevator chain wears and elongates, and a belt stretches during service life. A chain also elongates when handling hot materials. Therefore, a take-up adjustment is needed to maintain tension between the head and foot shafts. A manually adjusted screw take-up that moves the tail shaft or head shaft or a self-adjusting weighted take-up that maintains a constant gravity force on the tail shaft may be used. 

To check for soft foot, place a dial indicator onto the machinery foot, and loosening the base bolt. If the indicator moves more than 0.002 inches, the foot is soft and it should be corrected. Go through the same procedure on the remaining feet one at a time. 

Fig. 12. The morphology of spreading. Liquid advances over the solid by means of a precursor foot (usually a few to a few hundred nanometers in thickness) moving out typically several millmeters ahead of the nominal bulk liquid interline.

Infiltration rate. This is the rate at which air moves through a window system as a result of pressure differences between the inside and the outside. Infiltration rates are expressed as airflow rates—cubic meters per hour or cubic feet per minute per square foot of window. An infiltration rate below 0.3 cfm/sq ft is recommended in all applications. 

Move the dial indicator and holder to the next foot to be checked and repeat the process. Note The nuts on all of the other feet must remain securely tightened when a foot is being checked for a soft-foot condition. 

On the baseline, start at the left end and mark the stationary back-foot. From the back-foot and moving right, count the number of squares along the baseline corresponding to FFS. Mark the stationary front-foot location. 

Locate the FBM or back-foot of the movable component. Move either up or down vertically on the scale to the point of the offset measurement. Mark this point on the graph. Remember, positive values are above the horizontal baseline and negative values below the line. 

Stand with your feet apart, with one foot in the direction you intend to move. 

Far from a wellbore, the velocity of reservoir fluids is about one linear foot per day. Near a wellbore, the velocity can increase one-hundred fold. A static or quasi-static test such as the sessile drop (contact angle) test may not represent the dynamic behavior of the fluids in the field. The dynamic Wilhelmy device gives results which are comparable in interface velocity to the field displacement rate. The interface in the Wilhelmy test described here moved at a steady rate of 0.127 mm/sec or 36 ft/day. The wetting cycle for a hybrid-wetting crude oil system was not affected by moving at a rate less than 1 ft/day. 

Today s postal service is more efficient than ever. Mail that once took months to move by horse and foot now moves around the country in days or hours by truck, train, and plane. If your letter or package is urgent, the U.S. Postal Service offers Priority Mail and Express Mail services. Priority Mail is guaranteed to go anywhere in the United States in two days or less. Express Mail will get your package there overnight.
