When you pop a balloon by overfilling it with air, you are applying Boyles Law. When a nurse fills a syringe before she gives you a shot, she is working with Boyles Law. Sport and commercial diving. Underwater salvage operations rely on Boyles Law to calculate weights from bottom to surface. When your ears pop on a plane as it rises from takeoff, that's Boyles Law in action.
Yes if it was not practical it was not there. You can see the real life use on this link http://www.intmath.com/Applications-differentiation/Applications-of-differentiation-intro.php

you use math in everyday of your life !
some real life examples are a water bottle, pipes, cans
