Is the flow speed at Location 2 higher or lower than the flow speed at Location 1? d Location 1 Location 2 d2 O higher cannot tell from the data lower The flow speed at Location 1 is 1.87 m/s. What is the pressure difference AP between Location 2 and Location 1 (including its sign)? Ignore viscosity. AP = РаA level (horizontal) pipe contains a non-viscous, incompressible fluid with a density 1200 kg/m3 that is flowing steadily. At one position within the pipe, the pressure is 300 x 103 N/m2 and the speed of the flow is 20.0 m/s. At another position, the pressure is 200 x 103 N/m2.
