Small vessels can be motorized via the attachment of a boat engine (Fig. 2a). These boat engines power an impeller that sucks in water through an intake pipe, which exits through an outlet pipe as a water jet (Fig. 2b). Given the intake pipe has diameter Din = 6 in and the outlet pipe has diameter Dout= 3 in, and the intake pipe meets the outlet pipe at an angle α = 120◦, calculate the flow rate needed to produce a thrust force of 1000 N.
