A tractor drawn boom type sprayer fitted with 12 nozzles at a spacing of 50 cm is used to carryout spraying at a forward speed of 3.5 km.h⁻¹ and nozzle pressure of 250 kPa for an application rate of 1.5 m³.ha⁻¹. Out of the total discharge from the pump, 12% is bypassed to the liquid tank and the total pressure drop in all pipe lines from the pump is 10% of the pressure developed by the pump. Considering the pump efficiency as 60%, if the nozzle pressure is increased by 10%, the power required to operate the pump, in kW, is _______. (Rounded off to 3 decimal places)
