Draining a Bathtub Evangelista Torricelli was an Italian mathematician and physicist. He is best known for his invention of the barometer, but he is also well known for his law regarding the speed of fluid flowing out of an opening. For a bathtub with a rectangular base, Torricelli's Law implies that the current height h of the water in the tub t seconds after it begins draining is given by the equation 2ла? з h = lw where l and w are the tub's length and width, d is the diameter of the drain, and ho is the water's initial height.

Draining a Bathtub
Evangelista Torricelli was an Italian mathematician and physicist. He is best known for
his invention of the barometer, but he is also well known for his law regarding the speed
of fluid flowing out of an opening. For a bathtub with a rectangular base, Torricelli's
Law implies that the current height h of the water in the tub t seconds after it begins
draining is given by the equation
2ла? з
h =
lw
where l and w are the tub's length and width, d is the diameter of the drain, and ho is the
water's initial height. (All measurements are in inches.)
