Formula - (inches of water^0.5)*66.2

Can some one give me the "long hand" version of this equation.

Inches of water(^)????
Do i add water to .5 or do i times... .5x.5 Can't seam to get the right answer.

The carat ^ is the symbol used by most common spreadsheet programs for the exponent function so A^2 means A squared and inches of water^ 0.5 means inches of water to the exponent 0.5 which is just another way of saying the square root of the inches of water.

can you put it in an example so my pee brain can grasp it.

Sure, let's say the pitot pressure is 16 "WC, the velocity in fps is 66.2 x 16^0.5 = 66.2 x √16 = 66.2 x 4 = 264.8 fps.

BTW, have you seen my spreadsheet, haven't you?

I lost that one when i switch computers THANK YOU.

And thanks for spelling it out for me. I get it now, and the ## work, Yeah!

thanks again for your time
