The Pomdeterra wastewater treatment plant produces thickened sludge that has a suspended solids concentration of 3.8 percent. They are investigating a filter press that will yield a solids concentration of 24 percent. If they now produce 33 m^3/d of sludge, what annual volume savings will they achieve if they install the press?
The wastewater treatment plant for Pine City discharges 1 × 105 m3/day of treated waste to the Pine River. Immediately upstream of the treatment plant, the Pine River has an ultimate CBOD of 2 mg/L and a flow of 9 × 105 m3/day.
A 27ft beam has a uniform load of 6kip/ft. along its entire length. From left to right x=0ft to x=27ft. At x=0 ft it is pinned and at x=18 ft there is a roller. So, the 9 ft end section is cantilevered.
The total dissolved inorganic carbon (TIC) of a sample of groundwater is 8.33 mM. The temperature of the aquifer is 15C, the pH is 7.5, and the ionic strength is 0.05 M. What is the H2CO3, HCO3-, CO3 2-, and the partial pressure of CO2? [Use activ..
After a few drinks under exactly the same conditions, the driver fails to stop in time and strikes the object at a speed of 35 mi/hr. Determine the driver's perception/reaction time before and after drinking.
The velocity out of the tube may be approximated by V = √(2(p-patm)/ρ), where p is the absolute tank pressure. Determine the time at which the pressure (gage) in the tank is 20 kPa if the initial pressure is 40 kPa (gage)
a low rate trickling filter plant gives 95% BOD5 removal. the primary clarifier removes 33% of the BOD5 applied to it. the secondary sludge amounts to 0.029lb dry solid/cap-day. if the raw wastewater has a BOD5 of 0.17lb/cap-day.
the rigid bar abcd is supported by a pin at B and restrained by identical steel bars at C and D, each of area 250mm^2. if the temperature is increased by 80C, determine the force P that will cause the bar at c to be stress-free.
A 1 cm diameter, 0.4 m long steel rod is to be used in an application where it will be subjected to an axial tensile force of 15kN. The factor of safety based on yield stress must be at least 1.5, and the axial deformation must not exceed 2 cm.
A fully loaded, ocean going container ship is just stable about its longitudinal axis (roll). The ship has a total weight of 155,000 tons, length = 1,600 feet and a beam = 150 feet (assume that it is the shape of a rectangular box). Calculate the ..
A cylindrical metal specimen 12.0 mm in diameter and 120 mm long is to be subjected to a tensile stress of 40 MPa . at this stress level the resulting deformation is totally elastic.
The frame is desinged to carry the hanging mass at G equal to 167 kg. The frame is supported by a pin connection at C and the rope AB, and constructed with pin connections at points E, F, and D.
Water enters the lock of a ship canal through 180 ports, each port having a 2 ft by 2 ft cross section. The lock is 900 ft long and 105 ft wide. The lock is designed so that the water surface in it will rise at a maximum rate of 6 ft/min.
