Back in the Pre-Analysis section, we had predicted the power coefficient to be around 0.3. As seen on the convergence plot above, the numerical results do agree well with this value considering a sufficient number of elements in the mesh. For example, using a mesh of 2 million elementscells, the power coefficient becomes 38% as opposed to the 30% from hand-calculations. These match up quite well considering the many assumptions used in the simple 1D momentum theory.
