Water at 20°C(?=998.3?? ????=1×10−6?2/?)flows through a galvanised iron pipe (? = 0.15 ??) with a diameter of 20 mm, entering the room at point A and discharging at point C from the fully opened gate valve B at a volumetric flow rate of 0.003 m3/s. Determine the required pressure at A, considering all the losses that occur in the system described in Figure Q1. Loss coefficients for pipe fittings have been provided in Table 1. L1 = 4 L2 = 1 L3 = 2.66 L4 = 1.34 L5 = 0.5 L6 = 1 Loss Coefficients Gate valve (fully opened) - 0.19 90 deg elbow - 0.9 45 deg bend - 0.4 Tee for valve along branch - 1.8
