4. The system in Fig. consists of 1200 m (length) of 0.05 m (diameter) cast iron pipe, two 45° long-radius elbows, four 90° flanged long-radius elbows, and a fully open globe valve. If the elevation at point 1 is 400 m, what gage pressure is required at point 1 to deliver 0.005 m³/s of water at 20°C into the reservoir? Average surface roughness of cast iron is ε = 0.26 mm. For water at 20°C, take density, p = 998 kg/m³; dynamic viscosity, μ = 0.001 Pa-s; and acceleration due to gravity, g = 9.81 m/s².
