A 30° reducing elbow is shown below. The fluid is water. Evaluate the gage pressure at section 1 and components of force (Rx, Ry) that must be provided by the adjacent pipes to keep the elbow from moving. Elbow mass, M 10 kg Internal volume,= 0.006 m³ Q=0.11 m³/s P1 = ? A₁ = 0.0182 m² V₂ 30° P2 15 kPa (gage) A₂ = 0.0081 m²
