Question:
- A fully developed flow is established in a circular pipe of diameter d = 0.1 (m). A velocity probe is inserted into the pipe flow, with negligible obstruction that is a distance Δr = 0.01 (m) from the pipe wall and reads a velocity u = 0.8 (m/s). If the flow is assumed to be laminar determine the following.
- (a) Sketch the internal pipe flow arrangement. (3 Marks)
- (b) Assuming laminar pipe flow determines the maximum velocity umax (m/s) of the fluid flow in the pipe, the average velocity has (m/s) and the flow rate Q (m3/s). (7 Marks)
- (c) Is the laminar flow assumption valid, if the working fluid is air at T = 20 °C?
