Hi, my name is Mark Anthony and I reside In Gibraltar. I am a fire-fighter within this country and I am currently studying to do exams in March with the institute of fire engineers in the U.K. I am studying for a science paper within the Membership field and I have come across the topic of Bernoulli's equation which I am having quite a problem in understanding. The equation is used in order to find out pressures differences, and for measuring flows in pipes.
Could it be possible to give me some information in order to solve questions concerning the above?
Dear Mark, You may find the following articles from Issue 1 useful:
I just wanna know exactly what a googol is? And Infinity. I know these might be dumb questions for you all but if you don't mind I would appreciate the help. Thanks a lot.
We published an explanation of the googol in our issue11 letters page.

What a great site!
I teach English to French third year maths undergraduates (amongst others) and find your site a great source of ideas.
Thanks, and keep up the good work. I'm almost tempted to take up maths again after 15 years' break!
Thanks for the compliments - it is always good to hear from people about how they use the site!
Can you help me with my maths homework?
The question is
I don't want the answer but I don't understand the question!
A good place to ask this sort of question is on the askNRICH bulletin board. (Go to http://nrich.maths.org, click on "askNRICH" in the menu bar, and post your question in the "Statue of Anonymous" topic.)
As for your homework, I think the question is likely to be:
"What is the value of when ?"
...and to work that out you simply replace with 2/3 wherever appears in the formula for . Then work out the answer.
