What is the magnitude of the maximum stress that exists at the tip of an internal crack having a radius of curvature of 5.5× 10-4 mm (2.165 ×10-5 in.) and a crack length of 3.5 ×10-2 mm (1.378 × 10-3in.) when a tensile stress of 200 MPa(29010 psi) is applied?
an operator at a wastewater treatment plant decided to increase the SRT from 5 days to 10 days. How will this change affect: a) the oxygen requirement b) MLVSS in the aeration tank.
use zero through forth order taylor series expansions to predict f(2.5) for f(x) = ln x using a base point at x=1. compute the true percent relative error for each approximation. discuss the meaning of the results.
A projectile is fired up into the air at a speed of 161 m/s at an angle of 64° relative to the horizontal. Determine the maximum height the projectile will reach.
In Chlorine disinfection (3-log reduction in Giardia- Cysts), determine the water pH for a contact time of 90 minutes using a chlorine concentration of 2 mg/L at 20 degrees C
Two activated sludge aeration tanks in Podunk, MO are operated in series. Each tank has the follwing dimensions: 7.0 m wide x 28.0 m long x 3.5 m effective liquid depth.

A wastewater treatment plant must disinfect its effluent before discharging the waste water to a near-by stream. The wastewater contains 4.5x10^5 fecal coliform colony-forming units (CFU) per liter.
Assume that there were 1,100,000 vehicles making a 28.5-mi round trip per day, the average vehicle emission rate for VOCs is 1.3 g/VM , and the molecular weight of the VOC emissions from the mobile sources can still be represented by that of metha..
The evaporation rate from the surface of a 3650-acre lake is 100 acre-ft/day. Estimate the depth change in the lake in feet during a 1-year period if the net inflow to the lake is 25 cfs. Is the depth increasing or decreasing
A crane is used to lift a concrete pipe weighing 10kN into place. For precision positioning, the worker at C can apply up a 800N force to cable AC. Determine the largest distance d the concrete pipe may be moved.
The saturation concentration for the drop is 9.20 mg/L. If, after falling for two seconds, the droplet has an oxygen concentration of 3.20 mg/L, how long must the droplet fall (from the start of the fall) to achieve a concentration of 8.20 mg/L
Drawdown data from an observation piezometer near a well used for a pumping test with constant pumping rate is plotted on a semilog plot vs. time (the time axis, on the horizontal, is on a log scale).
