application of fluid mechanics

why we learn fluid mechanics? Fluid mechanics is essentially the study of fluids either in motion (fluid in dynamic mode) or at rest (fluid in stationary mode). A fluid is defined as a material that continuously deforms under a constant load. There are five relationships that are most useful in fluid mechanics problems: kinematic, stress, conservation, regulating, and constitutive. The analysis of fluid mechanics problems can be altered depending on the choice of the system of interest and the volume of interest, which govern the simplification of vector quantities. By assuming that a fluid is a continuum, we make the assumption that there are no inhomogeneities within the fluid. Viscosity relates the shear rate to the shear stress. Definition of a fluid as Newtonian depends on whether th...

Guided wave pipeline inspection

the current inspection technology named LRUT is widely used by oil and Gas company. Basically, LRUT sometime called as Guided waves are mechanical stress waves that propagate contained within the structural boundaries of pipes or plates with wavelengths that are comparable to the thickness dimensions of the pipe or plate. LRUT / Guided waves are used by inspection company in rapid testing or Screening tools to detect, locate and classify corrosion defects. Large sections of pipeline / piping can be quickly screened with 100 % coverage to determine precise locations of metal damage. After conducted the screening, more detailed inspections can then be focused on the locations that are critical, thus saving money and time. These local inspections can be done using guided wave Scanning e...

welding inspector course

What is Welding Inspection? Welding inspection is the use of technological applications to inspect or assess the quality of the welds. It is also to confirm the presence, location and coverage of the welds. In the field of fabricator, the welds are used to connect two or more metal surfaces. As the welds carry the brunt of loads, it can encounter fatigue which may be detrimental if proper inspection is not carried out. There are many reasons as to why welding inspection should be carried out. However, the most prominent reason is to ensure that the welds are of the quality that will allow them to carry out their performance to the max. In most cases, quality of the welds is determined on the basis of which functions it performs. There are some few ways to tell if a weld is correct. Wh...
