A fluid flows downward with the rate of Q=0.015 m/s in a smooth vertical pipe with the length of l. (a) Find the diameter of the pipe if the pressure drop (p1- p2) is zero. (Hint: Use Moody Chart with the initial guess of f=0.02. Two iterations are enough) (b) If the pipe outflow hits a fixed vane as shown in the figure, what would be the horizontal and vertical forces (Fx, Fy) on the vane? (p = 1000 kg/m³; µ = 0.001 kg/m. s; a = 30 deg)
