Hi guys

I need to know what value to use for a Free convective heat transfer coefficient for air in a cylinder of diameter 0.0127 metres and length of 0.1778 metres.
I know the value is generally beetween 5 and 25 W/(mēK) but I jus want it to be as accurate as possible for my scenario.

Also what does it mean to have a high Free convective heat transfer coefficient for air rather than a low one?

Thanks.
