Is there any reputable calculation on the amount of water a large indeterminate plant needs a day assuming no rainfall?

Last year it rained enough that I didn't need much supplemental irrigaton. This year it has rained less than 2"

I installed a drip system and at this time my plants that have been in the ground for 3 weeks are getting a quart a day. WHen I return home in 2 weeks If the plants are sgnificantly larger I plan on doubling the amount of water per day every 2 weeks until I get to a gallon a day per plant. I think for most plants deep infrequent watering will develop deep roots, but for my tomatoes I think I will try the evenly moist method to reduce stress and maximixe yields.

Anyone know if my water use estimates are close to replace water used by growing tomato plants? It doesn't look like much rain is coming this year.
