Test: Continuity Equation in Two & Three Dimensions - Question 3

For incompressible fluid flow, if area reduces then what is the effect on the velocity.

Detailed Solution for Test: Continuity Equation in Two & Three Dimensions - Question 3

Explanation: According to continuity equation,
Area × velocity = constant
Hence, as area decreases velocity increases.

Test: Continuity Equation in Two & Three Dimensions - Question 4

For compressible fluid flow in a pipe, having decrease in specific gravity what will be the effect of decrease in diameter?

Detailed Solution for Test: Continuity Equation in Two & Three Dimensions - Question 4

Explanation: According to continuity equation,
ρ*A*v = constant
Hence, as density and area decreases velocity is bound to increase.

Test: Continuity Equation in Two & Three Dimensions - Question 5

What is the most common assumption while dealing with fluid flow problems using continuity equation?

Detailed Solution for Test: Continuity Equation in Two & Three Dimensions - Question 5

Explanation: In majority of the fluid flow problems, flow is assumed to be steady.

Test: Continuity Equation in Two & Three Dimensions - Question 6

The diameters of a pipe at the sections 1 and 2 are 8 cm and 13 cm respectively. Find the discharge through pipe if the velocity of water flowing through the pipe at section 1 is 6 m/s. Determine also the velocity at section 2.

Detailed Solution for Test: Continuity Equation in Two & Three Dimensions - Question 6

Explanation: According to continuity equation,
Area × velocity = constant
Area1*Velocity1 = Area2*Velocity2
Velocity2=(Area1*Velocity1)/Area2
= (82 * 6) / 132=2.27 m/s.

Test: Continuity Equation in Two & Three Dimensions - Question 7

The continuity equation can only be used for analysis of conserved quantity.

Detailed Solution for Test: Continuity Equation in Two & Three Dimensions - Question 7

Explanation: Continuity equation is defined on a control volume and hence, is applicable only to Conserved quantities.

Test: Continuity Equation in Two & Three Dimensions - Question 8

The diameter of a pipe at the section 1 is 9 cm. If the velocity of water flowing through the pipe at section 1 is 4.8 m/s and section 2 is 9 m/s, Determine the area at section 2. 

Detailed Solution for Test: Continuity Equation in Two & Three Dimensions - Question 8

Explanation: According to continuity equation,
Area × velocity = constant
Area1*Velocity1 = Area2*Velocity2
(Area1*Velocity1)/Velocity2=Area2
Area 2= 33.93 m2.

Test: Continuity Equation in Two & Three Dimensions - Question 9

 For a flow to be physically possible it must primarily satisfy which equation?

Test: Continuity Equation in Two & Three Dimensions - Question 10

Continuity equation can also be derived for polar coordinate system

Detailed Solution for Test: Continuity Equation in Two & Three Dimensions - Question 10

Explanation: Continuity equation in polar coordinate is also used for analysis.
