In water and wastewater treatment processes a filtration device may be used to remove water from the sludge formed by a precipitation reaction. The initial concentration of sludge from a softening reaction (Chapter 4) is 3 2 percent (20,000 mg/L) and the volume of sludge is 100 m. After filtra - tion the sludge solids concentration is 35 percent. Assume that the sludge does not change density during filtration, and that liquid removed from the sludge contains no sludge. Using the mass balance method, determine the volume of sludge after filtration.

A certain robot can perform only 4 types of movement. It can move either up or down or left or right. These movements are represented by 'U', 'D', 'L', 'R'. Assume all these movements to be of unit distance. Write a function named theRoundTrip that takes all the movements the robot made in a day as input and output True of bool type if the robot returned to its starting position after its journey. Otherwise, return False. If the input is bad print the message "bad input".

At a water-treatment plant, water at 20°C flows from tank A to tank B at a rate of 600 L/s through a 50 cm diameter asphalt lined iron pipe that is 150 m long. Determine the difference in water surface elevation between the tanks (open to the atmosphere) if there are three bends (R/D = 10.0) and a fully open lift type check valve in the pipeline.

The radiant energy incident on the earth's surface on a sunny day is roughly 900.0 W/m2. Collecting and focusing sunlight and using the focused beam to heat a fluid is an old idea, and as the environmental costs of fossil-fuel combustion mount, solar heating becomes an increasingly attractive alternative. Suppose a house is to be designed that will have a circulating forced-air central-heating unit, and solar energy is contemplated as a heat source (backed up with a conventional furnace to be used on cloudy days). If air is to be fed at a rate of 2000.0 m3/min at 30.0°C and 1 atm, and the air is to be heated to 60.0°C before being discharged into the living space, what is the required area of the solar collector plates? Assume 30.0% of the radiant energy incident on the plates is used to heat the air.
