I'm looking at building a jockey box with a 21.3m (70 ft.) 5/16" (8mm) stainless steel coil (installed in a drum-style cooler.) Seems to be a good compromise between size, weight and cost.

How quickly can I pull cold beer out of it without it foaming?

My back-of-envelope calculation says a 2133.6cm by 0.8cm coil holds π × 0.4² × 2133.6 = 1072³ or just over a litre of beer. The Mythbusters say you can cool a six pack of beer in five minutes with salted ice water, so I'd interpolate that one beer per minute would be achievable.

Can anyone confirm my theory with experimental evidence?

How quickly can I pull cold beer out of it without it foaming?

My back-of-envelope calculation says a 2133.6cm by 0.3125cm coil holds π × 0.3125² × 2133.6 = 654.5cm³ or a bit over six and a half litres of beer. The Mythbusters say you can cool a six pack of beer in five minutes with salted ice water, so I'd interpolate that one beer per minute would be achievable.

How quickly can I pull cold beer out of it without it foaming?

My back-of-envelope calculation says a 177.8cm by 0.3125cm coil holds π × 0.3125² × 177.8 = 54.54cm³ or a bit over 500ml of beer. The Mythbusters say you can cool a six pack of beer in five minutes with salted ice water, so I'd interpolate that one beer per minute would be achievable.
