Two waters are in equilibrium with air, one at pH 9.5 and one at pH 7.3. these waters are mixed in 1:1 proportions. Assuming that carbonate species dominate the acid/base behavior of boh solutions and that no gas transfer occurs when they are mixed, determine the alkalinity and pH of the mixture. Will the mixture be undersaturated, supersaturated, or in equilibrium with atmospheric CO2?
Describe the use of productivity models for estimating land productivity. Provide details about various attributes that can be used and how the model is developed . Examples can be used to demonstrate model workability.
SAMPLE B:has size 10,mean 20 and variance 36 .calculate pooled sample variance
Air (m=28.97kg/kmol) is uniformly heated at steady state as it flows through a cylindrical constant area duct. It enters the channel uniformly at 2.5atm, 300K and 80m/s and exits at 1.5atm.
The piezometer A is located 4,000 ft south of piezometer B. Approximately 3,000 ft of piezometer B there is a river with an elevation relative to sea level of about 455 ft.
determine the horizontal spacing of the vertical drains if the drains are installed in triangular grid to reach 90% of primary consolidation in 1.5 years after the commencement of fill placement
The influent flow is 380 Lpcd and the influent BOD5 is 200 mg/L. Pertinent data are: Primary clarifier removes 33% of the influent BOD5, and the state regulatory agency allows a volumetric loading of 0.48 kg BOD5 /(m3.day). Determine the reactor b..
A trapezoidal channel lined with d50 = 10 cm has a bottom width of b = 1.2 m, side slopes of m = 3, and a longitudinal bottom slope of S0 = 0.008. Determine the normal depth and the Froude number for Q = 1.4 m3/s.
The floor area of each floor in these buildings is 400 m^2. The buildings are separated by large lawns so that the (Exposure + Communication) factor = 1.2.
A 12 foot W14 X 22 column with pinned ends is axially loaded. The max load it can carry is 34 ksi. Determine (a) Euler buckling stress, (b) Euler buckling load. (A = 6.49 in^2) (ry = 1.04 in) (Iy = 7.00 in^4)
0.1 moles of an ideal gas contained in a piston-cylinder assembly undergoes the heat pump cycle shown below. The cycle operates counter-clockwise. Evaluate the coefficient of performance.
The motor-generators installed with these pump-turbines have an efficiency of 0.85 when operating as motors and 0.91 when operating as generators. Each pump-turbine uses its own 100-m-long, 150-cm steel penstock.
the engine develops a maximum torque of 210ft-lb at 3600 rev/min. what is the maximum grade this vehicle could ascend, on a paved surface, while the engine is developing maximum torque (assume that the available tractive effort is the engine-gener..
