3. () Water flows into the top of an open barrel at a constant mass flow rate of 30 lb/s. Water exits through a pipe near the base with a mass flow rate proportional to the height of water inside: M = 9L, where L is the instantaneous water height, in ft. The area of the base is 3 ft², and the density of water is 62.4 lb/ft³. The barrel is initially empty. a. Find out how the height of water changes with time (i.e. L(t)); b. Use Excel to plot the variation of water height with time;
