Water is discharging out of a tank via a pipe with length L = 4.6 m and diameter D = 3.5 cm into an unconnected reservoir (note the free-flowing jet starting at the end of the horizontal pipe section in the figure below). The water level in the tank above the centre of the pipe remains constant at H = 4.6 m (see figure below). You can assume a density of water p = 998 kg/m², dynamic viscosity of water u = 0.001 Pa·s and acceleration due to gravity 9.81 m/s. You can assume that there are no local losses. V H L,D a) What is the friction factor of the pipe for a flow rate of Q = 3.5 L/s? Provide your answers to 3 decimal places. f = A correct answer is 0.044, which can be typed in as follows: 0.044 b) For this case, what is the roughness height of the pipe? Provide your answers to 3 decimal places. A correct answer is 0.533, which can be typed in as follows: 0.533 ky = mm
