The arrangement shown in the figure measures the velocity V of a gas of density 1 kg/m 3 flowing through a pipe. The acceleration due to gravity is 9.81 m/s 2 . If the monomeric fluid is water (density 1000 kg/m 3 ) and the velocity V is 20 m/s, the differential head h (in mm) between the two arms of the manometer is ________.
