$[2$ marks$]$

b$.$ Differentiate a real fluid from an ideal fluid

$[2$ marks$]$

c$.$ Given an oil with a density of $981\frac{(kg)}{m^3}.$ The shear stress at a point in oil is $0\mathrm{.}2452\frac{N}{m^2}$ and velocity gradient at the point is $0\mathrm{.}2$ per second. Compute

i$.$ Dynamic viscosity

$[5$ marks$]$

ii$.$ Kinematic viscosity

$[3$ marks$]$

c$.$ A Newtonian fluid is filled in the clearance between a shaft and a concentric sleeve. The sleeve attains a speed of $50\frac{(cm)}{(s)}.$ When a force of $40$ N is applied to the sleeve parallel to the shaft. Determine the speed if a force of $200$ N is applied

$[8$ marks$]$

TOTAL: $[20$ MARKS$]$
