Applied Project: How Fast Does a Tank Drain? Question 4: Part b) (DTube)

In this video I go over part b) of Question 4 of the Applied Project: How Fast Does a Tank Drain? This example continues from my last video, which was part a), and uses the differential equation developed in that video for a spherical water tank, to evaluate the time it takes for the tank to completely drain out of water. Although I don't solve the equation of the water height explicitly, it is still good enough to determine it explicitly as a function of time because it still allows us to evaluate specific heights at specific times. Also in the video I do a lot of calculations by hand as opposed to simply using a calculator, so make sure to watch this video if you want to also see a good exercise in algebra and calculations by hand!
