A tar me how he width 0.25 m and length - 1.50 m. The trough is open on top A constant row of ethanol (density 790 km 5 to the trough at a rate of 20 L/min Ethan ses them the top urce of the trough at a constant rate or 0.0001 m. Ethanol is also drained than the promom of the truth at a rate that is proportional to the instantaneous depth of ethanol in the trou (A The drainage rate in unit of mis 0.0005h, where his in m. Assume that the truth is deep Onth that the ethanol does not spill out. If the trough is initially empty, find (a) the final steady-state depth of ethanol in the trough, and Grader use only! (1) the time it takes to fill the trough to half the steady state 4 3 depth (b) 3 Total: 18 0 Pipe Open top Evaporation Inflow Container T Water Drain how to L Drainage
