Show how the following list of binary numbers would be sorted by radix-2 sort, with a cutoff to insertion sort on the last 2 bits of the numbers. (show the list after each pass of radix sort and after the insertion sort pass.) 1010 1101 1011 0101 0100 0110 1110 1001

Amixture of slurry and mud is to be pumped through a horizontal pipe of diameter 500 mm. the fluid behaves as a bingham plastic with a yield stress of 30 pa and viscosity 0.04 pa.s. describe the effects of the shear stress through a transverse section of the pipe by plotting the variation in shear stress and velocity profile: (i) just before the slurry starts to move (ii) as the slurry flows when the pressure gradient is double that in part (i)
