#### Pascal Second is a unit of

SI unit of Dynamic viscosity is Pascal Second or Ns/m2 or Poise SI unit of Kinematic viscosity is Stokes or m2/sec 1 stoke = 10^(-4) m2/s 1 poise = 0.1 pa.s

#### An ideal fluid is

Ideal fluid is incompressible and have no viscosity. Onlu imaginary Fluid

#### The unit of Kinematics viscosity is

1 stoke = 0.01 cm2/sec = 0.0001 m2/sec

#### If the dynamic viscosity of a fluid is 0.5 and specific gravity is 0.5, then the Kinetic viscosity of the fluid in stoke is

Kinematic viscosity = DynamicViscosity/SpecificGravity = 0.5/0.5 =1

#### The viscosity of a gas

Viscosity for gas increases with increase in temperature. Viscosity for liquid increases with decrease in temperature.

#### Newton's law of viscosity relates

T=u.du/dy

#### The rise of liquid of specific weight γ in a capillary tube of radius r is given by, where σ is the surface tension of the liquid

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

ΔP = 2σ/d for jet ΔP = 8σ/d for soap bubble ΔP = 4σ/d for droplet = 4 x 0.075/0.075 x 10^-3 = .004 N/mm2 = 0.4 N/cm2

#### Surface tension of water

#### 1 kilo Pascal is equal to

1 Pascal = 1 N/m2 Kilo = 10^3 1 kilo Pascal = 1000 N/m2

#### Abe liquid has greater Cohesion than adhesion with the solid, then the liquid in the capillary tube will

Capillary fall if Cohesion is greater than adhesion. Rise if Adhesion>cohesion

#### Examine the following for 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. Capillarity is due to both Cohesion and adhesion Of the following statements are true

#### Pressure of 200 kPa is equivalent to a head of X metres of carbon tetrachloride of relative density 1.59 where x is equal to

Density = 1.59*water density = 1590 kg/m3 P = pgh 200x10^3 = 1590*9.81*h h = 12.82 m
