Problem

The viscosity of a liquid flowing in a pipe is doubled while its density and the pipe radius remain unchanged. To reach the onset of turbulence, the average flow speed must be (a) vnew=v02v_{\text{new}}=\dfrac{v_0}{2} (b) vnew=2 v0v_{\text{new}}=\sqrt{2}\,v_0 (c) vnew=2 v0v_{\text{new}} = 2\,v_0 (d) vnew=v0v_{\text{new}} = v_0
