A 1.60 m cylindrical rod of diameter 0.550 cm is connected to a power supply that maintains a constant potential difference of 17.0 V across its ends, while an ammeter measures the current through it. You observe that at room temperature (20.0 ∘ C ) the ammeter reads 18.8 A , while at 92.0 ∘C it reads 17.3 A . You can ignore any thermal expansion of the rod. Part A Find the resistivity and for the material of the...

A rectangular, well-mixed aeration lagoon is 75 m long, 5 m wide, and 2 m deep. It receives 400 m3/d of wastewater with a BOD5 of 367mg BOD5/L for treatment. The biodegradation rate constants for the wastewater are the following: yield coefficient = 0.8 mg VSS/mg BOD5, endogenous decay constant = 0.08 d-1, maximum specific microbial growth rate = 1 d-1, and half velocity constant = 76.0 mg BOD5/L. What must the hydraulic detention time be in the aeration...
