    12. Good Day I want some advice regarding a borehole installation. I am a mechanical engineer working at a mine. We are going to be installing a new dewatering borehole in July. The hole in 250 meters deep, and we will be installing a 300 cubic meter pump. The pipe we ordered is a stainless steel pipe that is fabricated in 6.1 meter segments. we are looking at an outside diameter of 193.7 mm and a 5.8 mm wall thickness for the pipe. We are planning one welding reducing sockets to the ends of the pipes and machining male and female threads so that each section can screw into the next. But due to the length of the borehole, and the skew nature of boreholes, we will need the joining sections to be flexible somehow without compromising the strength of the assembly. Now my question is, has anyone come across a similar project? I need some drawings of a similar design to present to the consulting engineer firm we are going to use so they do not start from scratch. I could draw up the design myself, but am not sure of the design. I am hoping there is someone out there who can provide me with an idea, or drawing of such a pipe splicing. Or maybe just point me in the right direction. any feedback will be appreciated

    16. Hi I have a doubt I am studying strain of the materials and I wanted to know is there are internal forces when the bodyt is in equilibrium and if so, this is at the molecular level

        Without a doubt there are all manner of internal forces at the molecular level whether the body is in equilibrium or not. These forces are not of engineering interest. We can do nothing with them. We cannot change them, control them, or do anything else. Also, they do not affect anything of engineering concern.

        When we talk about strain, then that implies internal forces caused by stretching and deforming the material. The forces associated with elastic strain are released when the deformation is removed. The forces associated with plastic strain are not fully released when the external load is removed. This is the reason it is sometimes necessary to stress relieve a part after manufacturing, to remove the locked up internal stresses.

    24. Read the entire thread again and you will understand my point. If nothing else read your comments Nov 22 2015. How I arrived at this thread just a few days ago that started months ago I am not sure.
    25. The word you want here is "follow," not fallow. To follow is to go with someone or thing, to go where they go. "Fallow" is an adjective that describes a field left for a season to rest without a crop.

    28. I am working now on 

      Performance evaluation of steam injected gas turbine power cycle.

       

      the aims are 

       

      1.    Investigate the effect of steam injection on SGT-500 Industrial Gas Turbine through thermodynamic analysis.

      2.    Develop a detailed thermodynamic model and consider the limit of steam injection in relation to the operating limit for the SGT-500 gas turbine.

       

      I am strangling in someways anyone could help. 

    29. Should I learn Autodesk AutoCAD as a Mechanical Engineering Student?. Or which softwares should I learn?

        hi, 

        this was a question for me also. I suggest you learn CATIA or PTC CREO. these are widely used in industries.

        You should expect that, no matter which software you learn today, it will soon be out of date. In ten years you will be using a software system that does not exist today. That's life.
