3m3 on the one hand to a tank with Liquid fluid is fed with 3m3/min flow rate, on the other hand, ltt is discharged with the help of the outlet pipe as in the figure. The output flow rate varies linearly with the level. and the resistance of the valve is 2min/m2. According to this, a) Find the transfer function that gives the ratio of the level to the input current flow rate. b)what happens if Inlet flow suddenly goes from 3m3/min to 3.5m3/min, the level that was originally(in the beggining) 3m Find out how does it change in time. c) What will be the last value the level will reach? How long will it take to reach this last value
