Higher-Order ODES A U-tube manometer (used to measure pressure) is filled with water and exposed to a pressure difference such that the water level on one side is at y = 0.02 m measured from its equilibrium position. At time t=0 the pressure difference is suddenly removed, and the water level in the tube will begin to oscillate up and down, and it will eventually settle at an equilibrium position. Initial: At equilibrium: 1 U The ODE that describes the water level function of time in the U-tube manometer is: Ly" = -0.5y'-2gy - - - - y represents the displacement with respect to the equilibrium position and is a function of time t y' represents the velocity and is a function of time t y" represents the acceleration (a function of time t) L = 0.25 m is the total length of the tube g=9.81 m/s is the acceleration due to gravity program RK4sys(a, b, nsteps, xa, ya, x, y) integer j; real h, t, k11, k12, k21, k22, k31, k32, k41, k42 xxa; yya; ta h(b-a)/nsteps for k=1 to nsteps do kll h*xp(t, x, y) k12 hyp(t, x, y) k21h*xp(t+h/2, x+k11/2, y + k12/2) k22 hyp(t+h/2, x+k11/2, y + k12/2) k31h*xp(t+h/2, x + k21/2, y + k22/2) k32 hyp(t+h/2, x + k21/2, y + k22/2) k41h*xp(t+h, x + k31, y + k32) k42 hyp(t+h, x + k31, y + k32) x+x+11+2k2,1 + 2k3,1 + k4,1] y+y+12+2k2.2 + 2k3,2 + k4,2] 1+1+h output h, j,t, x, y end for end program RK4sys Create a dictionary: rename y ---> x (displacement), and y' ---> y (velocity), and derive the set of functions needed to solve the second order ODE by replacing it with a system of two first order ODEs. Considering that the system starts from the position shown on the left figure (y = 0.02 m, v = 0 m/s), determine the position, velocity, and acceleration of the fluid on the left side of the tube at t = 1.2 s using a) Taylor series of 4th order, manual calculations, 1 step b) Runge-Kutta of 4th order, manual calculations, 1 step
