John has two identical water barrels in his backyard. One day during the self-isolation period, he gets bored and rigs up a short spout at the bottom of each barrel, which allows it to freely drain out into his yard. The barrels are identical in every way, except one barrel has a sharp edge where the inside of the spout interfaces with barrel. On the other barrel, John has filed down that same corner so that it has a soft fillet (i. e. rounded edge).
Which barrel will drain faster?
