Water is pumped from the tank shown in Fig. P5.82a. The head loss is known to be 1.2 V²/2g, where V is the average velocity in the pipe. According to the pump manufacturer, the relationship between the pump head and the flowrate is as shown in Fig. P5.82b: h_p= 20 - 2000 Q₂, where hp is in meters and Q is in m³/s. Determine the flowrate, Q.
