You have designed a treatment system for contaminant z. the treatment system consists of a pipe that feeds into a cstr. the pipe has a volume of 15 m3 and the cstr has a volume of 60 m3 . the inflow is 10 m3 /d and the influent z concentration is 2,500 mg/l. if the effluent from the cstr has a z concentration of 500 mg/l, what is the degradation

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)
