Simple model for new product sales that contemplates the effect of success and competition.
Sales initially grow as the new product moves from introduction into growth. Sales success attracts competitors who introduce their own products which reduces sales growth of the new product.
Eventually the total number of products that the market can bear are sold which stops further sales.
More advanced models could contemplate how competition affects price, how new successful products from competitors take market share, etc.

This model fills a bathtub, while outflow occurs at a flow determined by the volume of water (or pressure at outlet) of the bathtub. It could just as well be a dam or lake that is modeled.

Exercise 1. The bath is initially empty. Water flows in through the tap at a variable rate (L/min) and flows out through the drain at a constant rate (30 L/min). The tap is controlled using a slider at 5 minute (300 second) intervals.
