You meet with a potential client to discuss a land development project. Your client wants to know the capacity (in cfs) of the existing water supply system serving the area With a 450-ft pipeline, the current system delivers water from a reservoir to a storage tank. The tank is open to the atmosphere. The water level of the reservoir is 150 ft above that of the tank. The intake end of the pipeline is square-edged (k=0.5) and the water coes into the tank through a submerged end (k=1). You are told that the pipe is 12 in in diameter and the roughness is approximately e=0.005 ft. The average temperature in this area is 60 F. Using the Moody Diagram and the trial and error method, estimate the capacity of the existing system.
an existing water treatment plant is producing an average flow of 0.5 mgd. due to several limitations the plant only
In the determination of the average velocity of flow in wide rivers, it is common practice to estimate the average velocity in a vertical section by making a single measurement at a distance below
Draw a diagram of the room with all of the important parameters noted with symboles. Write a material balance to describe the rate of change in the amount of benzene in the air of the room starting from the time the bottle was opened onwards.
A 2 m diameter semicircular channel made of brickwork is to transport water to a distance of 1.7 km uniformly. If the flow rate is to reach 200 m3/min when the channel is full, determine the minimum elevation difference across the channel.
A rinsed and dried filter weighed 0.3588 grams before the sample was filtered and then weighed 0.3630 grams after the sample was filtered and being at dried at 103C. What is the TSS for this sample
Presedimentation can reduce the suspended solids concentration of raw river water from 500 mg/L to 200 mg/L. How many pounds of dry solids does this represent per million gallons?
A particular mixed flow pump is operating just below the point of cavitation. The pump is sited with its intake 3 m above the water level in the reservoir and delivers 0.05 m3/s.
A barge measures 10 ft (depth) by 35 ft by 120 ft and weighs 100 U.S. tons. The barge floats in fresh water (specific weight = 62.4 lb/ft3) and is evenly filled with 38,000 bushels of corn (60 lb/bushel).
The interior height of the cone is 3.60 in. The cone has an exterior radius of 1.25 in and an interior radius of 1.10 in. The scoop of ice cream sits on the cone's interior radius and extends into the cone some distance.
Elongation (in %) of steel plates treated with aluminium are random with probability density function f(x)={x/250 20
The "supersoaker" water gun can shoot more than 30 ft in the horizontal direction. Estimate the minimum pressure, , needed in the chamber in order to accomplish this. List all assumptions and show all calculations.
A small community wishes to construct an activated sludge wastewater treatment plant to treat their wastewater. the wastewater from the community has an average flow rate of 0.0022 m^3/s (190 m^3/day) and an influent substrate concentration of 250 mg..
