Air (density 1.2 kg/m³) flows through a horizontal pipe with negligible energy loss due to friction. The flow is steady and incompressible. The average velocity and pressure at a certain cross section in the flow are 40 m/s and 220 kPa respectively. If the velocity at some other cross section is 30 m/s, what is the pressure? O 570.0 kPa O 220.4 kPa O 226.0 kPa O 219.6 kPa O 640.0 kPa
