A fluid, with a density of rho = 1165 kg/m3, flows in a horizontal pipe. In one segment of the pipe the flow speed is v1 = 4.53 m/s. In a second segment the flow speed is v2 = 1.77 m/s. What is the difference between the pressure in the second segment (P2) and the pressure in the first segment (P1)?
