A liquid has a constant density of $800$kg$/$m$^3$ is flowing at steady state through a section of pipes. At the entrance to the section p$=300$ kPa and v$=10$m$/$s and the pipe diamter is $10$ cm$.$ At the exit to the section, the pipe diamter is $20$ cm and the exit is also $5$ meters lower in altitude compared to the entrance

$,$determine the volumetric flow rate, velocity and preussre of the liquid at the exit
