3. The figure shows a cylindrical tank through'a long pipe and the velocity in it can be computed as: 2gH v = /2gH tanh 21 Where: v = 5 m/s = velocity of water g = 9.81 m/s? = gravitational acceleration t = 2.5 m = elapsed time L = 4 m = pipe length H= initial head Create a script file for Bisection Method to solve the unknown initial head (height of water) and with initial guesses x = 0 and xu = 4m then use e, = 10-7. Report your answer accurate to 6 decimal places.
