Near the end of the pipeline transporting a viscous flu

Near the end of the pipeline transporting a viscous fluid (γ = 900kg / m3; υ = 1 * 10-4 m2 / s), with a diameter of d = 0.15m, there is a Ludlo gate valve. Determine the piezometric pressure in front of the valve at a flow rate of Q = 0.04 m3 / s when the valve is moved by ¼. At the end of the pipeline, the pressure is atmospheric.
Given: Q = 0.04m3 / s; d = 0.15m2
