A 90° pipe bend with inlet diameter 0.4 m and exit diameter 0.3 m carries 0.5 m³/s oil of sp. gr. 0.85 with a pressure of 118 kN/m² at inlet to the bend. The volume of bend is 0.1 m³. Find the magnitude and direction of the force exerted by liquid on the bend. Both inlet and outlet sections to be at same vertical level. The oil enters the bend at 45° to the horizontal.
