Coolship
,→Inoculation Surface Area
====Inoculation Surface Area====
The ''top'' surface area to volume ratio affects the inoculation rate. Some brewers may want their coolship inoculation rate to be somewhere near what commercial coolships are. An example to find the SA:V ratio of just the top surface using the same two coolship dimensions follows:
<code>
:Example of a 36 bbl coolship:
::Surface area of the top surface of the wort (w x l) = 100 sq. ft.
::Surface Area to Volume ratio = 100/150 = '''0.67''' sq. ft. per cubic foot (22.0 cm<sup>2</sup> per L)
:Example of a 10 gallon coolship:
::Surface Area to Volume ratio = 6.25/1.25 = '''5''' sq. ft. per cubic foot (164 cm<sup>2</sup> per L)
</code>
The example above shows that the shallow 10 gallon coolship also has a much larger ''top'' surface area to volume ratio.
