For axial flow through a circular tube, the reynolds number for transition to turbulence is approximately 2300 based on the diameter and average velocity. if d = 3.6 cm and the fluid is kerosene at 20°c, find the volume flow rate in m3/h that causes the transition. for kerosene at 20°c, take rho = 804 kg/m3 and μ = 0.00192 kg/m⋅s. take π = (22/7) and round the final answer to two decimal places.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
