The velocity of water v(m/s) discharged from a cylindrical tank through a long pipe can be computed as: v=2gHtanh(2L2gH) where g=9.81m/s2,H= initial head (m),L= pipe length (m), and t= elapsed time (s). We would like to determine H needed to achieve v=5m/s in t=2.5s for L=4m. Use initial guesses of H1=0 and Hu=2. (a - 5 pts) Plot the function with Python between H1 and Hu (use a step of 0.1 ) (b) Find H with a stopping criterion of a
