The water pressure of a sink has a steady flow of 2 cups per 10 minutes for the first 30 minutes. It still flows at 2 cups per 10 minutes for the next 30 minutes after. For the next hour, the water pressure maximizes to 4 cups per 10 minutes and stops. Shawn now has to dump half of the water away. How much water is left? Let's think step by step and output the final answer after "####".

For the first 30 minutes, 3*2=<<3*2=6>>6 cups of water came out.
For the next 30 minutes, 3*2=<<3*2=6>>6 cups of water came out.
For the next hour, 6*4=<<6*4=24>>24 cups of water came out.
A total of 6+6+24=<<6+6+24=36>>36 cups of water came out.
Shawn had to dump water which left 36/2=<<36/2=18>>18 cups of water.
