Answer:
a) t = 165 days
b) 9.9 kg/day
Explanation:
Given data:
final lelvel of BOD is 20 mg/l
Ks = 100 mg BOD/L,
kd = 0.10 day-1 ,
μm = 1.6 day-1 ,
Y = 0.60 mg SS/mg BOD
a) we know that
solving for t
t = 165 days
b) mass of microbes
Answer:
Supply, demand, global markets, imports and exports, and government Regulation.

Answer:
the heat transfer from the pipe will decrease when the insulation is taken off for r₂<
where;
r₂ = outer radius
= critical radius
Explanation:
Note that the critical radius of insulation depends on the thermal conductivity of the insulation k and the external convection heat transfer coefficient h .
The rate of heat transfer from the cylinder increases with the addition of insulation for outer radius less than critical radius (r₂< ) 0, and reaches a maximum when r₂ = , and starts to decrease for r₂< . Thus, insulating the pipe may actually increase the rate of heat transfer from the pipe instead of decreasing it when r₂< .
Answer:
Smaller impurity atom will nullify some of the compressive strain of a dislocation in a crystal. Because, smaller impurity atoms located near a dislocation creates tensile strain on atoms around it thereby partially nullifying compressive strain at the dislocation.
