Water is flowing at4.00m/s in a horizontal pipe under a pressure of220kPa. The pipe narrows to half its original diameter. Assume laminar non-viscous flow.
(a) What is the speed of flow in the narrow section? m/s
(b) What is the pressure in the narrow section? kPa
(c) How do the volume flow rates in the two sections compare?
The volume flow in greater in the narrow section.The volume flows are equal.The volume flow is smaller in the narrow section.
