Water p$=1000$kg$/$m$^3$ enters a frictionless pipe that has a $2$cm diamter with a velocity of $9$ m$/$s and a pressure of $500$ kPa absolute$.$ The pipe has two sections. The first section is constant in diamter $2$ cm but climbs to a height that is $10$ meter higher than the entrance. The second section is an expander that is oriented horizontally, and the diamter increases from $2$cm to $8$cm$.$ The water is flowing at a steady state throughout the pipeA$)$ find the absolute pressure of the water at the end of the first section $($WHERE it ENTERS the expander$)$B$)$ find the velocity and the absolute pressure of the water when it exits the expander
