Question

$For the laminar flow of 20°C water in the circular pipe shown, find: a) the velocity at $ r = 4.0 \, \text{cm} $. b) $ v_{\text{max}} $ c) volume flow rate **Diagram Explanation:** The diagram illustrates the cross-section of a circular pipe with water flowing through it. The flow is described as laminar, which means it follows smooth streamlines. - The pipe has a radius $ R = 6.0 \, \text{cm} $. - A parabolic velocity profile is shown, indicating higher velocity at the center and lower near the walls. - The radial coordinate $ r $ is perpendicular to the pipe's axis, marked upwards in the diagram. - The flow direction is indicated by arrows pointing from left to right, labeled with $ \text{H}_2\text{O} $. - The pressure gradient along the pipe is given by $ \frac{dp}{dz} = -50 \, \text{Pa/m} $, showing a linear decrease in pressure along the pipe's length. This setup allows us to investigate aspects of fluid dynamics such as flow velocity and volume flow rate in a cylindrical coordinate system.$
