Some more numbers to throw out:
Situation:
cow on grass
2 bonus grassland tiles
industrious civ
Irrigating gets the first settler out 4 turns sooner if you don't build any warriors before the settler. (This is where being expansionists is great-and playing with no barbs).
Irrigate cow first then mine the bonus grasslands gets you 3 settlers by ~turn 31 or so. Mining the cow gets you 2 settlers by ~the same time. This is if the worker mines/irrigates, and then builds a road.
If doing an OCC, or doing some sort of early military rush with just your capital at the start (no population loss from building settlers/workers):
Mining the cattle outproduces (accumulated shields) the irrigation until ~turn 30, but irrigating will produce more shields/turn by ~ turn 15.
(this will vary depending on how many shield producing tiles you have to use-I was basing this on having bonus grassland).
