I need to know how caffiene intake effects urine output, obviously urine output will decrease, but by how much?

If 2000 ml of water was ingested, how much urine would be produced?
If 2000 ml of coffee was ingestedhow much urine would be produced?

Thank you for using the Jishka Homework Help Forum. Biology is not my area but I can tell you that caffeine is a diuretic, which means it increases urine output beyond fluid intake. Keeping well hydrated is important for good health. Sorry that I can not help you with the math part!
