Question 49
MENAT2 marksNeeds review
A pitot tube connected to a U-tube mercury manometer measures the speed of air flowing in the wind tunnel as shown in the figure below. The density of air is 1.23 kg m
while the density of water is 1000 kg m
. For the manometer reading of
mm of mercury, the speed of air in the wind tunnel is __________ m s
(rounded off to 1 decimal place). Assume: Specific gravity of mercury =13.6. Acceleration due to gravity = 10 m s
.
