Water flows downhill through a 10 cm diameter steel pipe. The slope of the hill is such that for each 1.5 km of horizontal distance, the change in elevation is dz meter. Determine the maximum value of dz if the flow is to remain laminar, with a temperature of T=20°C and pressure all along the pipe is constant.
