MECHANICAL PROPERTIES OF FLUIDS

Fill in the blanks using the word from the list appended with each statement:

(a) Surface tension of liquids generally … with temperatures (increases / decreases) 

(b) Viscosity of gases … with temperature, whereas viscosity of liquids … with

temperature (increases / decreases)

(c) For solids with elastic modulus of rigidity, the shearing force is proportional

to … , while for fluids it is proportional to … (shear strain / rate of shear

strain)

(d) For a fluid in a steady flow, the increase in flow speed at a constriction follows

(conservation of mass / Bernoulli’s principle)

(e) For the model of a plane in a wind tunnel, turbulence occurs at a … speed for

turbulence for an actual plane (greater / smaller)
