The characteristics curve (Head – Capacity relationship) of a centrifugal pump is represented by the equation ∆Hpump = 43.8 - 0.19Q, where ∆Hpump 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 ∆Hpiping (in m) is related to the water flowrate QL (in m3/h) by the equation ∆Hpiping = . The flowrate (in m3/h, rounded off to the first decimal place) of water pumped through the above pipeline, is _______
