Air enters from ambient atmosphere into a level duct of uniform cross-section area 0.2 m² at a flow rate of 2.0 m³/s and density of 1.2 kg/m³. The entry shock loss factor is 1.0 and the resistance of the duct per meter length is 1.0 Ns²/m⁸. The static pressure measured at a distance of 20 m from the duct entrance in Pa, is __________. (round off to 1 decimal place).
