HW$6-3$: Water flows through a circular nozzle and exits into the air as a jet, as shown in the schematic below. A manometer is attached across the converging portion of the nozzle, measuring the pressure drop. The volumetric flow rate is $2$ liters$/$second and the relevant diameters for the nozzle regions are given in the schematic. Assuming steady, inviscid, onedimensional flow within the nozzle, answer the following: $($a$)$ What is the velocity in section $1,($b$)$ What is the velocity in section $2,($c$)$ Determine the mercury manometer height, $h.($d$)$ What type of pressure is characterized by the manometer height, $h?$ Is it dynamic pressure, static pressure, or stagnation pressure?
