Math Question

I've got a forumla at work to figure out and I can get the exponetial right. What is 200 raised to the 0.5 power?

Apologize on the double post - didn't mean to. Hit "post" to soon when correcting my "guidance" here.

 

It so happens that the default Microsoft calc doesn't have a square root function.

BTW: answer is 14.142135623730950488016887242097 Hopefully that is accurate enough for you.

 

I'm using Win2K and the Scientific and Standard views of the calculator (calc.exe) have this function.

 

Unless I am blind, XP calculator does not:

 

yeah for xp and im guessing the rest of the series, it doesn't coem with the sqaure root button. But I know almost 99% of the physical calculators out there do. You can also go to www.calculator.com

 

the X Y button does this.. Y is your parameter, in this case 0.5

 

oh yeah gees can't believe I missed that one.

 

Thanks for the answer guys. Didn't know Win 2K had the scientific funtion to it.

Anyways, the answer I got was 5.3955415242913291844693740611316 for the entire formula.

The forumla is L=0.0001351ND(P raised to the 0.5 power)

N=353
D=8
P=200

This forumla is for calculating acceptable leakage in a 5100 linear ft. 8" water main. 200 is the psi at which the 2 hr test is, 353 is the number of joints that are in the line.

Anyone able to check my math?

 

Just FYI:
The xcalc comes fully equipped with a square root key, reminds me of the Texas Instruments TI 32. Now, that's a calculator!

BTW:
Isn't it pretty?

 

Wait a minute!
Its got it, but in a more general way...
in the exponent function...

x^y

key, you can find the square root (or other powers).
For the square root, enter (1/2) or 0.5 for the y value....
