1. a spherical storage tank has a radius of 3 meters and contains a drain plug at the bottom with a radius of 3 cm. using fluid mechanics principals, an ode of the change in height in time is given by the following equation: ℎ − ℎ 2 ) ℎ = −√ℎ where is the radius of the storage tank, is the cross-sectional area of the drain, and is a unit less experimentally determined value based on the type of fluid. use = 9.81, = 0.6, and an initial height of 5.9 meters. run the ode23 solver for 3 hours, you will get negative height results, delete these values. produce a single plot of the results and confirm that it matches the solution in your previous homework (no specific confirmation step required, but if it does not match you may not have used the function correctly). print the time it took to drain in the following format using fprintf: it took hh: mm: ss to drain.
