If most wildfires are suppressed (all fires are put out) for many years, how does the risk of wildfire in the area change in the future? There will be a higher risk of wildfires
There will be a lower risk of wildfires
There is no difference in risk

Explain your answer.

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)
