Entrepreneurship Skills – Overview
The Skills You Need to Build a Great Business What makes someone a successful entrepreneur? It certainly helps to have strong technology skills or expertise in a key area, but…
Surface tension of liquids
Surface tension of liquids is the many hydrostatic phenomena in which the surface tension of liquids plays a role, the most significant is probably capillarity. Consider what happens when a…
Archimedes’ principle
Consider now a cube of side d totally immersed in liquid with its top and bottom faces horizontal. The pressure on the bottom face will be higher than on the…
Differential manometers
The simplest such instrument is a U-tube containing liquid, as shown in Figure 1A. The two pressures of interest, p1 and p2, are transmitted to the two ends of the…
Hydrostatics
It is common knowledge that the pressure of the atmosphere (about 105 newtons per square metre) is due to the weight of air above the Earth’s surface, that this pressure…
Basic Properties Of Fluids
Fluids are not strictly continuous media in the way that all the successors of Euler and Bernoulli have assumed, for they are composed of discrete molecules. The molecules, however, are…
Fluid Mechanics:
Fluid mechanics is the study of the effects of forces and energy on liquids and gases. Like other branches of classical mechanics, the subject subdivides into statics (often called hydrostatics)…
Kill Sheet
International Association of Drilling Contractors (IADC ) is one of important organizations in drilling industries. One of their main contributions is well control. IADC has the well control courses and…
Kicks
A kick is a well control problem in which the pressure found within the drilled rock is higher than the mud hydrostatic pressure acting on the borehole or rock face.…
What is slug mud?
Slug Mud: It is heavy mud which is used to push lighter mud weight down before pulling drill pipe out of hole. Slug is used when pipe became wet while pulling…
