A 1000-gallon water tank is used for experiments in the field. Water is pumpedfrom a local creek at a rate of Qin = 40 gallons/minute (gpm) into the tank. Water dischargesthrough an outlet in the tank, but this only occurs when the volume V is greater than 200gallons. When above this level, the rate at which water leaves the tank (in gpm) depends onthe volume in the tank according to the following relationship:???? =(0.05/minute)*(V-200)If the tank starts off empty, develop a mathematical model for V versus the time t, then solvefor the time that it will take to fill up the tank to 800 gallons. (Hint: the model can be adiscontinuous function, so use mass balances for V both before and after water begins exitingthe tank).
