Cooling a computer

A small cluster computer has a total heat dissipation of $11,680$ watts.

How large an air conditioner $($in BTU$/$hr$)$ will be needed to handle the heat load?

What's a "scuff"?

A Standard Cubic Foot $($SCF$,$ "scuff"$)$ of natural gas is one cubic foot of methane at $60$F$,1$ atm.

The heat of combustion of methane is $802\mathrm{.}3k\frac{J}{m}ol.$

Assuming methane under these conditions is an ideal gas,

how many BTU per SCF does burning methane produce?
