If you were to put a can of "canned air” into a campfire, it would explode at a temperature of roughly 450° Celsius. If the initial temperature of the can
was 15° Celsius and the initial volume of the can was 750 mL, what will
the size of the resulting fireball be when it explodes?

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
