Test: Fluid Properties - 1 - Question 1

If the dynamic viscosity of a fluid is 0.5 poise and specific gravity is 0.5, then kinematic viscosity of that fluid in stokes is

Detailed Solution for Test: Fluid Properties - 1 - Question 1

μ = 0.05 Ns/m2
G = 0.5
∴  ρ = 0.5 x 1000 = 500 kg/m3

∴ 
= 1 cm2/s = 1 stokes

Test: Fluid Properties - 1 - Question 2

In a sample of water an increase of pressure by 18 MN/m2 caused 1% reduction in volume. The bulk modulus of elasticity of this sample, in MN/m2 is

Detailed Solution for Test: Fluid Properties - 1 - Question 2

Bulk modulus of elasticity
k = Δp/(Δv/v) = 18/1/100
= 1800 MN/m2

Test: Fluid Properties - 1 - Question 3

The rise of liquid of specific weig ht ‘γ’ and  surface tension ‘σ’ in a capillary tube of radius ‘r’ is given by

Detailed Solution for Test: Fluid Properties - 1 - Question 3

Height of capillary rise is given by,

Test: Fluid Properties - 1 - Question 4

Work done in blowing a soap bubble of diameter 12 cm will be. Assume the surface tension of soap solution = 0.04 N/m.

Detailed Solution for Test: Fluid Properties - 1 - Question 4

The soap bubble has two interfaces
∴ Work done
= 0.04 x 4π x (6 x 10-2)2 x 2
= 36.2 x 10-4 Nm

Test: Fluid Properties - 1 - Question 5

The intensity of pressure developed by surface tension of 0.075 N/m in a droplet of water of 0.075 mm diameter is

Detailed Solution for Test: Fluid Properties - 1 - Question 5

Pressure inside the liquid droplet is given by
 Δp=4σ/d  

σ is the surface tension = 0.075 N/m = (0.075/100) N/cm
d is the diameter = 0.075 mm= (0.075/10) cm

Therefore, pressure = [4 x (0.075/100)] / [0.075/10]
= 0.4 N/cm2

Test: Fluid Properties - 1 - Question 6

Two fluids 1 and 2 have mass densities of p1 and p2 respectively. If p1 > p2, which one of the following expressions will represent the relation between their specific volumes v1 and v2?

Detailed Solution for Test: Fluid Properties - 1 - Question 6

Specific volume(v) is defined as the volume(V ) per unit mass(m).
v = v⁄m = 1 / m⁄v = 1⁄p
where p is the mass density. Thus, if p1 > p2, the relation between the specific volumes v1 and v2
will be represented by v1 < v2.

Test: Fluid Properties - 1 - Question 7

Surface tension of water

Detailed Solution for Test: Fluid Properties - 1 - Question 7

In general, surface tension decreases when temperature increases because cohesive forces decrease with an increase of molecular thermal activity. The influence of the surrounding environment is due to the adhesive action of liquid molecules that they have at the interface.

Test: Fluid Properties - 1 - Question 8

A Newtorian fluid fills the clearance between a shaft and a sleeve, when a force of 0.8 kN is applied to the shaft, parallel to the sleeve, the shaft attains a speed of 1.5 cm/s. If a force of 2.4 kN is applied instead the shaft would move with a speed of

Detailed Solution for Test: Fluid Properties - 1 - Question 8


Test: Fluid Properties - 1 - Question 9

Consider the following statements:
1. Surface tension is due to cohesion only.
2. Capillarity is due to adhesion only.
3. Surface tension is due to both cohesion and adhesion.
4. Capillary is due to both cohesion and adhesion.

Which of these statements are correct?

Test: Fluid Properties - 1 - Question 10

If the relationship between the shear stress τ and the rate of shear strain du/dy is expressed as τ = k(du/dy)n then the fluid with a value of exponent n > 1 is known as
