  Following the recent study on the emergent Friedmann equation from the
expansion of cosmic space for a flat universe, we apply this method to a
nonflat universe, and modify the evolution equation to lead to the Friedmann
equation. In order to maintain the same form with the original evolution
equation, we have to define the time-dependent Plank constant, which shows that
the spatial curvature of $k=0$ and $k=1$ is preferable to $k=-1$ since the
Plank constant of the nonflat open universe is divergent. Finally, we discuss
its physical consequences.
