A horizontal pipe carries a smoothly flowing liquid with density 1.27 × 103 kg/m3. At locations 1 and 2 along the pipe the diameters are 5.35 cm and 2.91 cm, respectively.The flow speed at location 1 is 1.65 m/s. What is the pressure difference between location 2 and location 1 (including its sign)? Ignore viscosity
