The speed of the vaccine (p=1100 kg/m3) is held in a reservoirwhere a high pressure pushes it out. The pressure on the surface ofthe vaccine in one gun is 4.1x10^6 Pa above the atmosphericpressure outside the narrow opening. The dosage is small enoughthat the vaccine's surface in the reservoir is nearly stationarydurning an inoculation. The vertical height between the vaccine'ssurface in the reservoir and the opening can be ignored. Find the speed at which the vaccine emerges?
