![SOLVED: Show that the length of development or entrance length Le for flow in a pipe of diameter D varies as L/D Re for laminar flow and L/D Re^0.8 for turbulent flow. SOLVED: Show that the length of development or entrance length Le for flow in a pipe of diameter D varies as L/D Re for laminar flow and L/D Re^0.8 for turbulent flow.](https://cdn.numerade.com/ask_images/0e66413eed3e4ea08d80c07ec5db6f86.jpg)
