A Conveyor is essentially an infinite order exponential delay. This insight illustrates how increasing the order of an exponential delay begins to approximate a conveyor. The 10th order delay very closely aligns to the Delay 10 Conveyor.

This model of a single simple shower is based on a 1994 paper by John Morecroft et al of the London Business School. It is used to show the impact of delay on control of a simple system.
