1. A cylindrical tank with a valve at the base empties at a rate described by dy =-kul where y is the height of the tank, t is time, and k is a constant that depends on various factors including the tank's cross-sectional area, the shape of the valve, density of the fluid, and viscosity of the fluid If k=0.075, and the tank initially has 2 m of fluid, how long would it take to empty the tank? Apply Euler's method to solve this problem, you may use the computer package of your choice. a Generate plot of height of the tank versus time for at least 5 different time-step (h) values b. What is the largest time-step that can predict how long would it take to empty the tank to the second
