InterviewSolution

1.	The arrangement shown in the figure measures the velocity V of a gas density1 kg/m3 flowing through a pipe. The acceleration due to gravity is 9.81 m/ s2. If the manometric fluid is water (density 1000 kg/m3) and the velocity V is 20 m/s, the differential head h (in mm) between the two arms of the manometer is____________20.4
Answer» The arrangement shown in the figure measures the velocity V of a gas density 1 kg/ $m^{3}$ flowing through a pipe. The acceleration due to gravity is 9.81 m/ $s^{2}$ . If the manometric 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____________ 20.4
