The characteristics curve (Head – Capacity relationship) of a centrifugal pump is represented by the equation ΔH_pump = 43.8 - 0.19 Q, where ΔH_pump is the head developed by the pump (in m) and Q is the flowrate (in m³/h) through the pump. This pump is to be used for pumping water through a horizontal pipeline. The frictional head loss ΔH_piping (in m) is related to the water flowrate Q_L (in m³/h) by the equation ΔH_piping = 0.0135 Q_L^2 + 0.045 Q_L. The flowrate (in m³/h, rounded off to the first decimal place) of water pumped through the above pipeline, is _______
