Q2 Oil with a density of 850 kg/m³ and kinematic viscosity of 0.00062 m²/s is being discharged by a 6-mm diameter, 45-m-long horizontal pipe from a storage tank open to the atmosphere. The height of the liquid level above the center of the pipe is 3 m. Disregarding the minor losses, determine the flow rate of oil through the pipe.

Question 2A large vat contains water, which contains a drainage pipe at a height h1, as shown infigure 2. The drainage pipe has a length L. = 0.4 m, and a radius R = 15 mm, and releaseswater to the atmosphere at a flow rate Q. The connection between the pipe and the vatwall has a loss coefficient of KL = 0.8.Point A is in the middle of the tank at a height, hi.You can assume that the flow in the drainage pipe is fully developed and laminar. The density of water is p = 1000 kg/m° and the viscosity is u = 1 mPa.s. The acceleration due to gravity is 9.81 m/s? a) Find an expression for the pressure at point A.b) Find an expression in terms of Q, L, d, K, p and u for the pressure losses along the pipe (including the losses at the inlet and exit).c) If the flowrate out of the drainage tank is Q = 50 L/min, find ho. You may assumeany change of ho with time is negligible.

Water at 15 degrees Celsius is flowing through a 2-in ID smooth pipe. The friction loss for a 100-ft section of the pipe amounts to 4.8 lbf/lbm. Determine the velocity of the flow.
