A group of engineers tested four water nozzles at two different pressures. The table shows the average flow rate for each nozzle at 30 kilopascals (kPa) and 60 kPa. The engineers further established that, for each nozzle, the relationship between pressure and average flow rate is perfectly linear for pressures between 20 kPa and 80 kPa, inclusive.
