Urine through the day

The kidneys of a healthy adult made filtrate at a steady rate all day, but the share taken back changed with what the person drank. The day is split into six blocks of four hours. You will find the urine made in each block, the total for the day, and the block with the most urine. Then the program draws a bar for each block.

The idea. The urine in a block is the filtrate times the part that is not taken back: filtrate * (100 - taken_back) / 100.

Your tasks.

1. Set urine to the litres of urine made in each block, rounded to 3 decimal places.
2. Set total to the urine for the whole day, rounded to 2 decimal places.
3. Set wettest to the name of the block with the most urine.
