SOME IMP. POINTS ON VISCOSITYYYY
* Streamline flow is more likely fr liquids with low density and high viscosity
*Turbalent flow is more likely fr liquids with large density and low viscosity
*With increase in temp. , viscosity of gases increases and Liquids decreses
*With rise in temp., the coeff. of viscosity of a gas inc.
*At normal presssure , the viscosity of a gas is independent of pressure bt fr low and high pressures , viscosity of a gas is directly prop. to the pressure....
*Viscosity of liquids increase with increase in pressure...
*The flow of liquid becomes turbulent wen velocity of a liquid exceeds critical velocity
*Venturimeter is used to measure the amt of flow of a liquid in a pipe
*Pitot tube is also used to measure the flow of liquids...
*Scent sprayer works on bernoulli's principle while hydraulic breakes works on pascal's law
*The working principle of pressure gauge is based upon bernoulli's theorem
Q = (pi) p r4 / 8 
L
L*The clouds float in air because OF THEIR LOW VISCOSITY....
hope these points helps u....self writtenn
CHEERS!!!!!!!!!!!!!!!!!
