The horizontal pipe length is 180 m and the vertical pipe length is 24 m in the fire protection system, which is formed with a water tower and pipeline, 1 threaded 90 ° elbow (Kd = 0.9) on the pipeline and 1 slide valve at the pipe outlet (fully open position Kv = 0.2). Since the pipe material is cast iron and its diameter is 4 ”(101.6 mm), determine the maximum flow rate in the pipe considering the losses. Assume that the water level in the tower remains constant and the kinematic viscosity of the water is 1.124x10-6 m2 / s. Show your readings by drawing on the attached Moody diagram.
