Water flows through a horizontal pipe at a rate of 0.01 m /s. The pipe consists of two sections of diameters 5 cm and 2 cm with a smooth reducing section. The pressure difference between the two pipe sections is measured by a fluid manometer that has S=14.2. Neglecting the viscous effects, determine the differential height of fluid manometer h (m) between the two pipe sections. 5 сm 2 cm S
