Bernoulli's Principle

[laurab]

Have you heard of Bernoulli's Principle? If so, what are your thoughts on it?:confused:

:roll: not quite sure what to do with birds?

[laurab]

The diploma I am (supposed to be) doing on Ornithology goes on about it :roll:

[cooltom28]

what diploma is it national,first?

[laurab]

It's not a high one Tom, it's the one by J C Biology.

[cooltom28]

just checked their website says its level 2 qhich is equivalent to a first diploma or g.c.s.e's :-D :mrgreen:

Hi Laura,

i've honestly never heard of it until reading this topic. i can't see how the principle fits in with what i've been taught about the circulatory system and blood pressure being higher in arteries and lower in veins, due to the differences in diameter among a few other things... makes no sense

Back again, makes more sense now:)

http://en.wikipedia.org/wiki/Bernoulli%27s_principle

fluid doesn't necessarily mean water, gas also behaves the same so the principle is quite relavent to bird flight, lower pressure above the wings and hig below due to differences in the speed at which air flows above and below them. this in turn gives the bird lift and enables flight.

also, i should have remembered... if you have a filter in a fishtank or pond that has a ventauri system built in, the way that works is also due to lower pressure in the water than n the air, thus air is sucked in and bubbles given out at the other end. the thing that is critical to this is the angle in which you approach the current, infront of the flow pressure would be high, so if a hole was inserted here then water would squirt out, however if approached from behind the pressure is low due to water moving away at speed, this then sucks air in and gives those lovely bubbles at the end.

solved my bit of confusion also.

if i say much more i'll confuse myself again

that website chris has listed is excellent always good for scientific research also ivis? website i good

[Waxbillman]

hello Tom i think you'll find the universities do not like that site, for academic writting

Hi TOm,

it's definatey not one i use at uni, only peer reviewed websites etc are reliable as a source of scientific research, and i'm pretty sure that isn't one of them

can i just ask -
and level 1 - being GCSE?
isnt level 2 - AS level?
And level 3 - A level?

Laura how are you finding the course, what is they get you to complete with it? considered that a few years ago but decided against it at the time.

Thanks
Dave

Hi Dave,

as far as i'm aware, level 2 is GCSE and level 3 A-level. AS level is the same as half an A-level, it's all on the same level (jesus level level level level:lol: )

as for level 1, not too sure, it'd probably be one of the SATS exams, most likely the ones taken in year 9, what those taken in year 6 count toward i have no idea.

ultimately, the higher you climb, the more irrelavent any previous grades and qualifications become. things such as this ornithology course though, while they probably are overlooked if looking for a job (unless specific to birds perhaps) they are damn useful in helping out your own understanding.

the Icthyology course that JC biology do is level 3, and equivalent to an A-level. i would have taken both myself however they get covered in more detail either next year or the final year at uni

Chris;)

[cooltom28]

it wouldnt suprise me if level one was lower than than they do city and guilds here which i think is equiv to a g.c.s.e just below grade d?:roll:

[laurab]

Hi Dave - nice avatar ;)

The first assignment is to read a load of info, answer a ;oad a questions then write a report on what I have learnt.

Before I took it on I should have remembered that I haven't been to school for nearly 30 years! All i seem to know about these days is anti-social behaviour and housing law!

At least I have 3 years in which to complete the whole course. :lol:

[Waxbillman]

Matthew

ken

[Waxbillman]

oh reyt, never been there, i have passed near is a couple of times, and thought about it. it sounds great

[kenny]

hi matt
if you are thinking of going.make sure you get there early mate,there is far to much to see in a short day.i got there at 9 am and we were still going round at 7 pm.and you dont have to walk either.horse drawn tram old buses and trams are all free and run every 10 minutes it is well worth the entrance fee
