For an experiment where I must be able to control the pressure i attached to a syringe a 'chamber'. The inner diameter of the syringe is 19.3 mm and i will fill water to 17 cm of the syringe bottom (i call this P1), the spout has a inner diameter of 2 mm and a length of 2 mm (i call this P2) and the chamber where i want to know the pressure of has an inner diameter of 13 mm and a length of 3.5 cm (i call this P3) but i am interested of the prssure at 1.75 cm.
Water will constantly be flowing trough this setup which will be vertical, i will use a pump to keep the water level at 17 cm from the bottom of the syringe.
Must i take the fact that the diameter of P3 is smaller into consideration or also the fact that the diameter of P3 is smaller than the one of P1? If i ignore all of this and simply calculate the length form the top of the water surface which will be simply open to air to the point that i am interested in i get a pressure of 1.66 kPa (density of water x gravity x length). Any help is apriciated.
