Test: Applications of Bernoulli’s Principle - Question 1

Bernoulli’s theorem includes as a special case of:

Detailed Solution for Test: Applications of Bernoulli’s Principle - Question 1

Torricelli's law states that the speed of efflux, v of a fluid through a sharp-edged hole at the bottom of a tank filled to a depth h is the same as the speed that a body (in this case a drop of water) would acquire in falling freely from a height h.
This problem is solved using Bernoulli's equation,
gh+Patm/ρ​​=v2/2​+Patm
⟹v=√2gh​

Test: Applications of Bernoulli’s Principle - Question 2

Bernoulli’s theorem is important in the field of:

Detailed Solution for Test: Applications of Bernoulli’s Principle - Question 2

The Bernoulli equation is an important expression relating pressure, height and velocity of a fluid at one point along its flow.

Test: Applications of Bernoulli’s Principle - Question 3

Water is flowing through a horizontal tube. The pressure of the liquid in the portion where velocity is 2 m/s is 2 m of Hg. What will be the pressure in the portion where velocity is 4 m/s?

Detailed Solution for Test: Applications of Bernoulli’s Principle - Question 3

Test: Applications of Bernoulli’s Principle - Question 4

Air is streaming past a horizontal airplane wing such that its speed is 120 m/s over the upper surface and 90 m/s at the lower surface. If the density of the air is 1.3 kg/m3and the wing is 10 m long and has an average width of 2 m, then the difference of pressure on the two sides of the wing is

Detailed Solution for Test: Applications of Bernoulli’s Principle - Question 4

Applying Bernoulli's principle, we have
P1+1/2​ρv12=P2+1/2​ρv22 
⇒P2​−P1=1/2ρ (v2/1−v2/2)
⇒ΔP=1/2​×1.3× (1202−902)
⇒ΔP=0.65× (120+90) × (120−90)
⇒ΔP=0.65×210×30=4095Pa

Test: Applications of Bernoulli’s Principle - Question 5

In which of the following types of flows is the Bernoulli’s theorem strictly applicable:

Detailed Solution for Test: Applications of Bernoulli’s Principle - Question 5

Bernoulli's principle is applicable on those non-viscous liquids which have laminar flow or streamlined flow.
It means that a liquid in which its particles exert no force on each other, i.e., the speed of all the particles of the liquid is same.
Also, the liquid should travel in the form of streamlines, i.e., the liquid flowing in one pipeline (imaginary pipeline) should not mix in the liquid in another pipeline. This is called streamlined flow.
Also, turbulent flow is the opposite of streamlined flow. So, turbulent liquid will not obey Bernoulli's principle.
But if the liquid is rotated, this streamlined flow will not take place. Thus Bernoulli's principle will not be applicable to this type of liquid.

Test: Applications of Bernoulli’s Principle - Question 6

In the houses far away from the municipal water tanks often people find it difficult to get water on the top floor. This happens because

Detailed Solution for Test: Applications of Bernoulli’s Principle - Question 6

In the houses far away from the municipal water tanks often people find it difficult to get water on the top floor. This happens because a lot of water pressure is lost as friction between water and the pipeline.

Test: Applications of Bernoulli’s Principle - Question 7

Water is flowing through a pipe under constant pressure. At some place the pipe becomes narrow. The pressure of water at this place:

Detailed Solution for Test: Applications of Bernoulli’s Principle - Question 7

Given, That area of cross section at initial point is more than the final point,

From the equation of continuity, we can say that velocity at the final point is more than initial point.

Bernoulli theorem states that

At final point, the velocity is more, so the pressure will be less.

Therefore the pressure decreases

Test: Applications of Bernoulli’s Principle - Question 8

Water is flowing through a horizontal pipe in streamline flow at the narrowest part of the pipe:

Detailed Solution for Test: Applications of Bernoulli’s Principle - Question 8

Since Av has to be constant so as A decreases v has to increase and according to Bernaulli’s Theorem the sum of energies should be conserved. Since KE is high the pressure energy should be low.

Test: Applications of Bernoulli’s Principle - Question 9

To which type of fluid is the Bernoulli’s theorem applicable:

Detailed Solution for Test: Applications of Bernoulli’s Principle - Question 9

Bernoulli's theorem, in fluid dynamics, relation among the pressure, velocity, and elevation in a moving fluid (liquid or gas), the compressibility and viscosity (internal friction) of which are negligible and the flow of which is steady, or laminar.
Bernoulli's principle is applicable on those non-viscous liquids which have laminar flow or streamlined flow.
It means that a liquid in which its particles exert no force on each other, i.e., the speed of all the particles of the liquid is same.
Also, the liquid should travel in the form of streamlines, i.e., the liquid flowing in one pipeline (imaginary pipeline) should not mix in the liquid in another pipeline. This is called streamlined flow.
Also, turbulent flow is the opposite of streamlined flow. So, turbulent liquid will not obey Bernoulli's principle.
But if the liquid is rotated, this streamlined flow will not take place. Thus Bernoulli's principle will not be applicable to this type of liquid.

Test: Applications of Bernoulli’s Principle - Question 10

Bernoulli’s principle is based on the conservation of:

Detailed Solution for Test: Applications of Bernoulli’s Principle - Question 10

Bernoulli's principle can even be derived from the principle of conservation of energy. Bernoulli's principle states that, in a steady flow, the sum of all forms of energy in a fluid along a streamline is the same at all points on that streamline.
