In a 45-degree bend pipe on horizontal plane a circular air duct of 3.5 m^2 cross sectional area is gradually reduced to 1.2 m^2 area. Find the pressure in N/cm^2 at 1.5 m^2 cross sectional area, if the velocity of flow at the 2.1 m^2 section is 10.0 m/s and pressure is 3.453 N/cm^2. Take density of air is 1.18 kg/m^3.
