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...
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...
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...
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...
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...
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...
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...
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.
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...
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...
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...
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...
