Just Question 5, Thanks

4. [9 points ] At the end of operation of a cylindrical liquid phase batch reactor, the reactor contents are drained by a pipe at the bottom of the cylinder. The variation in the level of the liquid in the reactor, h, with time t is provided below. 1 Estimate the initial liquid level h(0) using the Matlab function spline. Estimate the time required to completely drain the reactor, tm, i.e., h(tm)=0. 5. [16 points] For the data provided in Problem 4, variation in h with t is predicted to be h(t)=(+t) Determine and using linear regression. After providing the setup for linear regression, use Matlab function regress to estimate and . Compute the absolute error and relative error vectors. Estimate the initial liquid level h(0) and the time required to completely drain the reactor, tm, and compare these with the corresponding values estimated in Problem 4 . 4.
