The application rate of an 18-nozzle hydraulic sprayer is 1120 L ha⁻¹. The nozzle spacing and forward speed are 400 mm and 3.4 km h⁻¹, respectively. The operating pressure is 2.1 MPa and the pump efficiency is 60%. If 10% of the pump output power is used for agitating the liquid, the power needed to operate the sprayer in kW (rounded off to three decimal places) is.
Correct : 2.950
