In a horizontal pipe with a gradually decreasing cross-section (in the direction of flow) there is a clear fluid of unknown density. The pressure at point P is higher than the pressure at point Q by 260 Pa. A technician measures the fluid's velocity at point P as 0.37 m/s, and that at point Q as 0.77 m/s. What is the density of this clear fluid, in kg/m^3?
