if air is blown with a speed of 15 m/sec across the top of one side of a u-tube containing water, the difference between the water levels on the two sides is 1.3 cm.
<h3>What is density?</h3>
The density is the ratio of the mass and volume of the particular object or liquid.
Applying the Bernoulli's equation across the ends of the tube A and B, we have
Substituting ρ = 1.2 , v = 15 and
In the left limb,
In the right limb,
The pressure at C and D are same.
Substituting from the above equations , we have,
h = -1.3 cm
The height to the left limb is greater.
The difference between the water levels on the two sides is 1.3 cm.
