1.A dairy that processes about 250,000 lb of milk daily produces an average of 65,100 gpd of wastewater with a BOD of 1400 mg/L. The principal opearations are bottling milk and maing ice cream with limited produciton of cottage cheese. What is the wasewater flow and BOD per 1000 lbs of milk recieved and calculate the BOD and hydraulic equivalent opulations of daily wastewater discharge.
2.A fresh wastewater containing nitrate ions, sulfate ions, and dissolved oxygen is placed in a sealed jar without air. In what sequence are these oxidized compunds reduced by the bacteria, and why is the substrate that is reduced first preferred by the hydrogen acceptor. When do obnoxious odors appear?
A large tank is used to calibrate the reading from a flow meter. Measurements of the system weight as a function of time are made. Water enters the tank vertically from the flow metering system at a speed of 20 ft/sec through a 1.5 in.
Determine the effective size as well as the uniformity coefficient and coefficient of curvature for each soil. Determine also the percentages of gravel, sand, silt, and clay according to (a) ASTM, (b) AASHTO, (c)USCS, and (d) the British Standard.
A pneumatic-tired tractor with a 354 - hp engine has a maximum speed of 3.6 mph in 1st gear. Determine the max. rimpull of the tractor in each gear if the engine effieicency is 91%.
A machine is supported on four steel springs for which damping can be neglected. The natural frequency of vertical vibration of the machine-spring system is 200 cycles per minute. The machine generates a vertical force p(t)=p0sinwt.
