An ideal fluid, of density 0.90 × 103 kg/m3, flows at 5.0 m/s through a level pipe with radius of 0.5 cm. The pressure in the fluid is 1.3 × 105 N/m2. This pipe connects to a second level pipe, with radius of 1.6 cm. Find the speed of flow in the second pipe.
Answer:
The speed of flow in the second pipe is 0.49 m/s
