Solution of Two Volatile liquids and Fractional Distillation

Volatile Liquid Fractional SeparationIf two volatile liquids are mixed to form a solution, the gas phase above the solution will contain molecules of both species and the vapor pressure of the solution is the sum of the vapor pressure of each component.

Functions and Properties of Drilling Fluids

Drilling FluidsThe function fluid must perform; the fluid properties that help to achieve these functions, and possible undesirable side effects that should be minimized. Unfortunately, fluid properties that are useful for the performance of one function may be determinate to another.

History of Drilling Fluid

Before going into detail of drilling fluid technology it is interesting to know the sequence of events which lead gradually to the various developments and ultimately resulted in the present stage when success of drilling a hole is attributed to be significantly depends on the better performance of a circulating fluid.

Introduction to Drilling Fluid (MUD) - Definition & Importance

The term mud originate from clay (native / commercial) suspension in water which were used initially to circulate out cutting from the hole during drilling operation and this term is still used widely in the drilling technology.

Stress And Pressure on Fluids

The forces that exist within a fluid at any point may arise from various sources. These include gravity, or the ‘‘weight’’ of the fluid, an external driving force such as a pump or compressor, and the internal resistance to relative motion...
