Engineering maths question on flow (venturi meter)

[From: ] [author: ] [Date: 12-03-30] [Hit: ]
from that? I thought the 1/2 was meaning half, which from above clearly doesnt.Anyone able to help out on how it gets that answer?......
I am doing a project on a venturi meter, and I am conducting a table of results from an expirement, however trouble I'm having is how a certain answer is worked out.

Differential Head = (h1 - h2) which is 232.5 - 26.0 = 206.0mm

That column is to be in 'm' so it ends up being 0.2060, which is fine so far. Then it goes to:

(h1 - h2)^1/2 = 0.2060^1/2 = 0.454m^1/2

Where does 0.454m^1/2 come from, from that? I thought the 1/2 was meaning "half", which from above clearly doesn't. It's had me stumped the last ten minutes

Anyone able to help out on how it gets that answer?

the ^1/2 is the same as taking the square root
