Design an algorithm that will take a list of numbers and partially reverse it, without making use of a second list variable. Starting at each end, the alternating entries of the list should be swapped. (Your solution may not use python's reverse function or slicing.) Example of the algorithm: Input

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)
