Water of density 1000 kg m⁻³ is pumped at a volumetric flow rate of 3.14×10⁻² m³ s⁻¹, through a pipe of inner diameter 10 cm and length 100 m, from a large Reservoir 1 to another large Reservoir 2 at a height 50 m above Reservoir 1, as shown in the figure. The flow in the pipe is in the turbulent regime with a Darcy friction factor f = 0.06, and a kinetic energy correction factor α = 1. Take g = 9.8 m s⁻². If all minor losses are negligible, and the pump efficiency is 100%, the pump power, in kW, rounded off to 2 decimal places, is ______
