Let's call that 35 billion lattes, because what's 1% between friends?.

Let's say those 35 billion lattes are consumed over a 35 year period. So 1 billion per year. Or about 2.7 million per day, or 31 per second. That's about 8L/s.

Alternatively, The USA apparently consumes about 400 million cups of coffee per day. So, 35 billion coffees is about three months of consumption.
