How much calcium bicarbonate (kg/day) will need to be added per day in water with alkalinity of 30 mg/L CaCO3 (assume for simplicity only bicarbonate alkalinity is present) if 794 kg of (Al2(SO4)3 x 18H20 is added per week to treat water with coagulation/flocculation in a water treatment plant with capacity of 1 million gallons daily.
Consider the following coagulation/flocculation (unbalanced) reactions occur:
Al^3+ + HCO3- --> Al(OH)3 + CO2
What is the reaction that occurs with hexanal and propanol (give both the hemiacetal and acetal products)?
The aluminum end and the copper end are maintained at temperatures of 50°C and 260°C, respectively. The thermal conductivities of aluminum and copper are 205 and 385 W/m · K, respectively. The temperature of the aluminum-copper junction in the rod..
An aluminum rod (1) (E=80 GPa, d=24.5 x 10-6/oC) and a brass rod (2) (E=115 GPa, d=22.0 x 10-6/oC) are connected to rigid supports. The cross-sectional areas of rod (1) and (2) are 4,000 mm2 and 5,000 mm2
Emissions of heat-trapping carbon dioxide (CO2) reached an all-time high of 31.6 gigatons in 2011, a 3.2% increase over 2010. The International Energy Agency said this further reduces the chance that the world can avoid a dangerous rise
In using the Darcy-Weisbach equation for flow in a pressure conduit, what percentage error is introduced in Q when f is misjudged by 20 percent?
The power loss, p , in a journal bearing depends on length, L; diameter, D; clearance, c; and rotational speed, w. You also have to worry about lubricant viscosity, density, and pressure. Obtain the dimensionless groups that charactrize this probl..
a piston-and-cylinder device contains 5 kg of water initially at 150 C and 0.20 MPa. The frictionless piston is then pushed slowly in an isothermal process until the volume of water becomes 10% of its initial value.
For a cantilever beam 20 ft long under a uniformly distributed load of 500 pounds/foot, calculate the deflection v and the slope dv/dx as a function of x by integrating differential equations.
The coefficients of static and kinetic friction are 0.3 and 0.2, respectively, between each of the plates and between plate A and the ground. Determine the acceleration of each plate.
using darcy's law compute the quantity of flow, seepage velocity and contaminant loading of the river. ground water is flowing through unconfined uniform 3m thick sand aquifer and discharging to river.
The slope of the channel So=.15% and the Manning n=.038. Estimate the depth y2=100m upstream of a section where the flow depth y1=2.2m Using a) the direct integration method and b) the standard step method.
A hole is drilled in an aluminum plate with a steel drill bit whose diameter is 6.245 cm at 20 degrees Celsius. In the process of drilling, the temperatures of the drill bit and plate rise to 168 degrees Celsius.
