    Keeping your Salary Confidential

    As has already been pointed out, it's in the company's interest not to publish salaries/raises, and it's generally in the employees interest (to some extent) to know what their peers are earning. So... what tends to happen (in my limited experience) is that the companies tell people not to...

    Uncompensated Overtime

    Your company's policy with regard to things like this - unless you work at a very small company where the individual can exert a large influence - is what it is, and you're probably not going to change it. Normally, I work around 40 hours a week. I have always been of the opinion that if I'm...

    impact of sphere on water

    rb1957 - yes, you're right. for final clarification the ball has a mass of 0.3kg. prex - yeah, i'd considered doing a drop test. I think we're sort of short on these things at the moment though so I'll wait until we get some spares in before I go breaking any more. Jistre - yes, the idea is...

    impact of sphere on water

    rb1957 - the mass is 0.3 kg (i.e. the product of it's density and volume). It's weight would be that value multiplied by gravitational acceleration, no? to explain a bit more history, this ball is used in a tool which is run down into the well. fluid is initially circulated through the tool...

    impact of sphere on water

    The terminal velocity did seem a bit high to me, but hey... it came from NASA. http://www.grc.nasa.gov/WWW/K-12/airplane/termv.html on the calculator there i used mass = 0.332 kg, CSA = 0.0026, altitude = 114m, drag coeff. = 0.5 (just looked this up as a typical [high] value for a sphere) I...

    impact of sphere on water

    Thanks for the input Don. Yes, I suppose to go down the road of complex fluid calcs may be overthinking things a bit. The ball is solid. It is 2-1/4" dia. made of phenolic plastic with a metalic filler. specific gravity of 3.4, so it weighs around 0.3 kg. I don't know the exact co-ef. of...

    impact of sphere on water

    Does anyone know how I can calculate the impact force/energy of a sphere falling onto a fluid? I know the geometry and mass of the ball, the height it has fallen (so can calculate a velocity at impact), and i know the properties of the fluid its being dropped onto. the real life situation is a...

    H4 wellhead profile

    Unfortunately the photocopier is probably a terrible idea in this instance - unless you want to go to jail for a long time. I would imagine, as drillernic says, that vetco would be the best source for this info.

    The $$$ on the Paycheque vs Going Home

    Time to sit down with the wife and she'll tell you what's going to happen...? :-)

    I don't want to work overtime!

    I don't have any experience of the American engineering/work culture (except by word of mouth from American colleagues) but 50 hr/wk seems excessive for an entry level position. Of course there will be times when workload dictates I have to work 50+ hours a week, but it shouldn't be the norm...

    what is the difference between a designer and an engineer

    I asked a draughtman at my company that very same question when I started work here, and his answer was "About 10 grand"...

    Job Interview - Technical Questions

    they gave me a drawing of a tool, and some operating conditions, and asked about the forces on certain parts of it, as well as general questions about it's design - any potential problems, etc. Then also a drawing of a section of a wellhead , and asked to design a tool from scratch to check the...

    Job Interview - Technical Questions

    Hey, got the job offer this morning - and still no mention of strawberries or bananas more's the pity!! For the record I'd opt to be a banana, but that's another story...

    Job Interview - Technical Questions

    Hi guys, I have a second interview for a job in a couple of weeks (having survived an assessment centre). They indicated that they would be asking some technical questions and I just wondered if anyone could shed any light on the sort of things you would ask if you were hiring a graduate...

    water injection in gas turbines

    yes, that would probably be options (b) and (c) then.

    water injection in gas turbines

    thanks for all the info and advice guys. i now have a few more details on this project i'm undertaking. it will be based on this (http://www.cussons.co.uk/en/products/p9005.html) dinky little educational GT set up we have in the lab. It consists of an old holset turbocharger unit to act as...

    water injection in gas turbines

    Does anyone know of any good sources of information on this topic? I am pretty much starting from zero here, and want to get a general idea of what it's all about before I start on the bulk of this undergraduate project I'm about to embark on. Any information about texts, online information...

    two quick questions

    firstly, im trying to generate 'random' numbers between zero and 49 (guess what for). currently im using: time_t t; srand(unsigned (time(&t))); int num = (rand() % 49); but as that stands, the numbers im getting dont seem very random. in fact they seem like theyre just being plucked from a...

    help me im a rookie....

    hi, i have an assignment to put 6 pseudo random numbers into an array to simulate drawing 6 lottery numbers between 1-49. the code i have to do this so far is listed below. i dont think its far off. im getting a recurring error regarding the syntax of my main() function argument calling in...

    exploding polylines

    i need to explode a series of polylines into their constituent parts to re-position certain aspects of my drawing, and i know that when you do this, you lose the width, and the plines become lines. is there any way of reassigning a width to these lines to make them polylines again without...
