A wastewater treatment plant that treats wastewater to secondary treatment standards uses a primary sedimentation process followed by conventional activated sludge process composed of covered aeration tanks and secondary clarifiers. You are asked to calculate the different operation parameters to make sure that the system is operated within normal process ranges listed in the reference tables below. Table 5-20 Typical design information for primary sedimentation tanks U.S. customary units Item Unit Range Typical Primary sedimentation tanks followed by secondary treatment...

Question 1 A turning operation is carried out on aluminum. Based on the specific energy values in Table 20.2, determine material removal rate and cutting power in the operation under the following sets of cutting conditions: (a) Cutting speed 5.6 m/s, feed 0.25 mm/rev, and depth of cut 2.0 mm; and (b) cutting speed- 1.3 m/s, feed 0.75 mm/rev, and depth 4.0 mm. Question 2 Consider a turning operation performed on steel whose hardness 225 HB at a cutting speed...

These data were collected from a slug test. The bottom of the well screen is level with the bottom of a confined aquifer. A pressure transducer in the well was used to make high frequency recordings of the water level height. The transducer is placed a short distance below the initial water level. The initial (pre-slug-insertion) level was 9.12 cm above the transducer. Screen length (m): 7.15 Well casing radius (m): 0.060 Screen radius (m): 0.15 Aquifer thickness (m): 6.75...
