$Assertion :$ The pressure of water reduces when it flows from a narrow pipe to a wider pipe.
$Reason :$ Since for wider pipe area is large, so flow of speed is small and pressure also reduces proportionately.

Pressure of water reduces when it comes from wide pipe to narrow pipe. According to equation of continuity, $av =$ constant. As the water flows from wider tube to narrow tube, its velocity increases. According to Bernouli prinicple, where velocity is large pressure is less.
