Chlorophenols impart unpleasant taste and odor to drinking water at con-centrations as low as 5 mg/m3. They are formed when the chlorine disin-fection process is applied to phenol-containing waters. What is the unpleasant taste and odor threshold in units of
(a) mg/L,
(b) tg/L,
(c) ppm,
(d) ppb?
Art Arfons, a K-State-educated engineer, has made a considerable fortune. He wishes to start a perpetual scholarship for engineering students at K-State.
At one of the entrances to the car parking area at the proposed new Mill project at Albion, a single line of vehicles approach a manually operated entry gate, where payment will be required to gain entry. The process of stopping at the payment ..
Determine the normal depth in a trapezoidal channel with a bottom width of 6.4 ft and side slopes of 1 vertical to 2 horizontal. The discharge is 85 ft3/s. Manning's roughness factor is 0.025 and the channel bottom slope is 0.001
The dimension h is to be determined so that a worker can comfortably slide boxes weighing up to 100lb up and downa frictionless incline. If the worker can apply a 50lb horizontal force to the box
A new disinfection process destroys coliform organisms in water using completely mixed flow reactor. the reaction is first order with k=1.0 per day. The influent concentration is 100 coli/ml. The reactor volume is 400L, and the flow rate (Q) is 1,600..
You have been asked to design a hoisting system and a demolition catch system for the superstructure of a bridge that you are removing. Discuss in detail the steps you would take in order to be able to provide the necessary information
What soil conditions favor the use of belled caissons? What soil conditions favor piles over caissons? What type of piles are especially well suited to repair or improvement of existing foundations and why?
A) Estimate the aquifer porosity and hydraulic conductivity, B) determine the flow rate per unit width of the aquifer, C) determine the specific discharge, D) determine average linear velocity of the flow assuming steady unidirectional flow
Water is pumped up 20 feet from one large, open tank to another large, open tank as shown in the figure below. The pipe connecting the 2 tanks has a total length of 200 feet and a diameter of 6 inches.
