Fluid mechanics

(C) based on newton's law of viscosity

    1. Newtonian fluid- Those fluid in            which Newton's law of viscosity            valid
        Ex-water,air,mercury,disel and                  petrol,kerosine oil etc
*According to newton

NOTE
√ in Newtonian fluid graphical nature is linear
√  in Newtonian fluid slope b/w shear stress and du/dy graph provide the value dynamic viscosity
√in Newtonian fluid viscosity of the fluid is constant

Q.determine the order of fluidity

  ANS-
   Fluidity order - A>B>C
   viscosity order - A<B<C

2.Non Newtonian fluid
   √study of non Newtonia fluid is               known as Rheology
    √non Newtonia fluid Newton's law        of viscosity not valid
    √non Newtonia fluid  behaviour            generally analysis by"ostwald's"

Where,
A=consistency index
n=flow behaviour index
B=yield stress
