A liquid of density 800 kg/m³ flows through a horizontal pipe that has a cross- sectional area of 200 cm2 in region 1 and a cross-sectional area of 700 cm² in region 2. The pressure difference between the two regions is 6000 Pa. Which region, 1 or 2, has higher pressure and why? What is the fluid's velocity in region 1 and 2, respectively? What is the mass flow rate?
