A desalination plant employs an electrical pump to raise water to a height of 37m to a treatment tank from a reservoir. The total pipe length is 437m, the pipe has a roughness factor of 0.21mm and the kinematic viscosity of water is 1.31x10^-6 m²/s. The required volume flow rate is 1757m³/hr and the pipe diameter is 2.1m. You can take the value of K_fittings = 12. Calculate Reynolds number for these parameters.

The answer should be to 3 significant figures.
