    Technical Superintendant in Vessel Management

    I am teaching English to person who as above. He manages a bulk carrier- coal, a car carrier and another vessel. What sort of discussions would he have the captain and chief engineer since these vessels are highly automated and monitored? Thank you in advance...

    Vertical mixed flow turbine pump selection

    Responders missed the key word in the original post- first time to do this SIZE of this type of pump (Not first time to do this type of pump). A magnitude up or down can be significant I do 1000 barrel/hr and this new application need 10 barrels/hr. Careful reading would have saved a whole heap...

    Yellowing of Polyarylate

    I think clandestinho wants to have some idea of how bad such a film will look after some time in the use. clandestinho- how long in sunshine (I assume) will this film be exposed and where? http://www.eng-tips.com/threadminder.cfm?pid=1529 Use translation assistance for Engineers forum Note...

    Which transparent plastics best reflect or absorb IR heat?

    You might want to be more specific about the infra-red frequencies that you are talking about reflecting or absorbing. Its a big spectrum. http://www.eng-tips.com/threadminder.cfm?pid=1529 Use translation assistance for Engineers forum Note the rules include No Student posting

    Tesla Autopilot, fatal crash into side of truck

    You'll still crumple zones, seat belts and air bags with a perfect self-drive. There are road disasters that reveal at such great rate e.g. truck's wheel disintegrates, train derails, that leave an instant reaction/ pre-prepared (expert precautionary) computer unable to fully prevent serious...

    Evaluating The Integrity Of Official Climate Records

    hydro test with fresh water

    The minimum size for a water drop is larger than drop of diesel due to hydrogen bonding and its related water surface tension- hundreds of molecules whereas a drop of diesel only dozens due to weak bonds. The minium size of drop doesn't matter since its impossible to have a hole in order of...

    Do We Know what "Renewable Energy" means?

    Carbon taxes (as are carbon credits) are rife with fraud. Imposing a tax on a invisible gas that everyone produces either deny everyone produces anything or just expect bogus claims of productions. Are you going to tax animals and nature which emits a lot- much which is difficult to quantify...

    Do We Know what "Renewable Energy" means?

    Its not novel to dry wood before burning. Livestock corn production competes with food production. Everything is renewable. http://www.eng-tips.com/threadminder.cfm?pid=1529 Use translation assistance for Engineers forum Note the rules include No Student posting

    Ferritic & martensitic steels: please help me to understand. . .

    All practical steels can form martensite. Its just a matter of a minimum level of carbon and suitable cooling rate from an austenitic state- its just that the so called ferritic steels require an excessive cooling rate that is hard to do and would cause cracking and distortion and the...

    Are concrete mix details required in drawing set?

    Surely an alternative is to specify the performance requirements as much as you need and design the mix but allow for professional operators to submit a counter mix to meet the performance requirements if they can sell you that it is cheaper/more practical in their particular local conditions...

    Zinc-Plated Brass

    It at the very least needs metal-metal contact- this doesn't sound there is- plastic jacket. Moisture is a not an decent electrical path only a decent ionic pathway so you can't get galvanic corrosion. And even if there metal/metal contact, you need to have the relative areas of the two metals...

    Does a Mixture of Gases Segregate by MW in a Vessel?

    I'd say no because thermal agitation of gas molecules at normal temperatures are more powerful than gravimetric separation thus it never separates. http://www.eng-tips.com/threadminder.cfm?pid=1529 Use translation assistance for Engineers forum Note the rules include No Student posting

    Qualification test for ultrasonic testing operator

    I'd think there would be standards would provide some assistance to qualification but the variety of possible ultrasonic inspection situations is too broad without reference to your particular needs for any standard, procedure or code to directly explain how to qualify. You'd need the...

    FCAW-G using DCEN vs DCEP

    You would need to specify as many parameters of the welds- geometry, welding parameters for anyone to estimate how much of mess you are in? Quality assurance checks.....
