Compression is WAY more difficult than the equation you selected, the pumping is also not adiabatic so there are inaccuracies.
I do love the 3 btus, sign me up for that one, though I stand by my number of 50,000 times 3.413 or about 150,000 BTUS.

I kept a constant v for simplicity, pretty much comparing the air in and out of the compressor if the inlet and exit manifold were equal in volume. Btu and watts are units of energy and power respectively.. Your 150,000 btu would actually be btu per hour. I didn't want to get into heat transfer lol.. Again just an estimate.
