Engineers are planning to build a highway that runs through a forest (0% impervious). However, the new regional regulations specify that the development of the area cannot increase the runoff of TKN (Total Kjeldakl Nitrogen) to the nearby river. The highway section going through the forest will be built of conventional materials (100% impervious), it is five miles long, and contains 4 lanes (12 ft wide each). The annual rainfall in the region is 41 in and 80% of the annual rainfall generates runoff. What is the annual TKN load increase due to the construction of the highway (in kg/yr)

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)
