A worker needs to pump water from a reservoir to a big container that is open to the atmosphere. The water velocity at the surface of the reservoir is 2.5 m/s. The worker uses a 35-m long, 18-cm diameter pipe with a friction coefficient of 0.013. He needed to use 2 threaded 90 regular bends, 2 threaded 45 regular bends, and one fully open angle. The elevation difference between the reservoir and the free surface of the tank is 3.5 m. The worker will use a pump with a curve represented by:

h = 45 - 9.5x10⁵Q² where h is in meters and Q in gal/sec.

Calculate the volumetric flow rate in m³/s at which the water is transferred to the tank at these conditions.
