In this situation, water is flowing horizontally in a pipe that has a diameter of 25cm. This water is flowing at 8 m/s and at 300 kPa gage it enters a 90 degree bend reducing section. This bend reducing section is connected to a vertical pipe that has a diamater of 15cm. Moreover, the inlet of the bend is 45 cm above the exit. Here, fricition and gravity are negligible and the momentum flux correction factor is 1.04.arrow_forwardConsider water flow through a horizontal, short garden hose at a rate of 30 kg/min. The velocity at the inlet is 1.3 m/s and that at the outlet is 11.75 m/s. The hose makes a 180° turn before the water is discharged. Disregard the weight of the hose and water.
