Calculate the resultant force, Fᵣ (kN) at a pipe taper if the force upstream in the direction of motion, F₁, is 51.6 kN, the force downstream opposing motion, F₂, is 14.2 kN, the density is 1000 kg/m³, the flowrate, Q, is 0.258 m³/s, the entrance velocity, V₁, is 1.08 m/s, and the exit velocity, V₂, is 3.51 m/s. Please give your answer to 3 significant figures.
