Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A branch of biology dealing with the relationship between living things and their environment.






2. A rough guess of the amount of flow in a collection system. When greater accuracy is needed - flow could be computed using average or typical flow quantities. Even greater accuracy would result from metering or otherwise measuring the actual flow.






3. The process of adding air to water. Air can be added to water by either passing air through water or passing water through air. In wastewater treatment - air is added to freshen wastewater and to keep solids in suspension. With mixtures of wastewater






4. Soil that cannot absorb any more liquid. The interstices or void spaces in the soil are filled with water to the point at which runoff occurs.






5. Railing support at landings or other breaks in the stairs. If an angle post projects beyond the bottom of the strings - the ornamental detail formed at the bottom of the post is called the drop.






6. A wall or plate placed in an open channel and used to measure the flow of water. The depth of the flow over the weir can be used to calculate the flow rate - or a chart or conversion table may be used to convert depth to flow. A wall or obstruction u






7. A break in a lateral pipe somewhere between the sewer main and the building connection.






8. A type of easement granting permission to a constructor or developer to build over a street or structure.






9. The running off of water from a land surface or subsurface - such as through sewers or natural means.






10. A trained builder or installer of landscapes - retained to implement the plans of landscape architects.






11. A reactor or basin in which baffles or other devices create a series of compartments. The environment and the resulting microbial population within each compartment can be controlled to some extent by the operator. The environmental conditions (food






12. An authorization issued by a government agency allowing construction of a project according to approved plans and specifications.






13. The used household water and watercarried solids that flow in sewers to a wastewater treatment plant. The preferred term is WASTEWATER.






14. Sand - silt - gravel and rocks carried or washed into a collection system by infiltration water flows.






15. A groundwater table that has seasonal changes in depth or elevation.






16. A material - other than aggregate - cementitious material or water - added in small quantities to the mix in order to produce some (desired) modifications - either to the properties of the mix or of the hardened product.






17. A strip of unspoiled - often treed - agricultural or other outlying land used to separate or ring urban areas.






18. The movement or dislocation of underground soil or structure. Earth shift is usually caused by external forces such as surface loads - slides - stresses or nearby construction - water movements or seismic forces.






19. A coordinating agency formed in 1961 for state boards that administer licensing exams and maintain records for landscape architects to practice.






20. A type of wastewater or service connection pipe made of a low grade of cast iron. _ In plumbing - a pipe that carries the discharge of toilets or similar fixtures - with or without the discharges from other fixtures.






21. A holding basin in which variations in flow and composition of a liquid are averaged. Such basins are used to provide a flow of reasonably uniform volume and composition to a treatment unit. Also called a balancing reservoir.






22. A site that might appear to be natural but has elements and features that were planned and specified by a landscape architect. Designed landscapes include Central Park in New York to the siting of buildings.






23. A chamber or well built at the curbline of a street to admit gutter flow to the storm water drainage system. Also see STORM WATER INLET and CATCH BASIN.






24. The amount of liquid which a solid material can absorb. Sand - as an example - can hold approximately onethird of its volume in water - or three cubic feet of dry sand can contain one cubic foot of water. A denser soil - such as clay - can hold much






25. A large - public park - often highly scenic and isolated belonging to and operated by the federal government.






26. Material used in backfilling of an excavation - selected for desirable compaction or other characteristics.






27. The property of a material or soil that permits considerable movement of water through it when it is saturated.






28. Rain and snow water accumulated in the earth's porous rock.






29. A sewer that receives wastewater from many tributary branches or sewers and serves a large territory and contributing population.






30. A network of pipes - manholes - cleanouts - traps - siphons - lift stations and other structures used to collect all wastewater and wastewatercarried wastes of an area and transport them to a treatment plant or disposal system. The collection system






31. A record of each person involved in the handling and possession of a sample from the person who collected the sample to the person who analyzed the sample in the laboratory and to the person who witnessed disposal of the sample.






32. A structure made of concrete or other durable material to protect bare soil from erosion by splashing or falling water.






33. British thermal units; the quantity of thermal energy required to raise one pound of water at its maximum density - 1 degree F. One BTU is equivalent to .293 watt hours - or 252 calories. One kilowatt hour is equivalent to 3412 BTU Back Pressure (wat






34. A septic tank or other holding tank which serves as a temporary wastewater storage reservoir for a Septic Tank Effluent Pump (STEP) system. See SEPTIC TANK.






35. A device that admits surface waters to the storm water drainage system. Also see CURB INLET and CATCH BASIN.






36. The science and management of land - especially rural - agricultural land.






37. Material used to fill in a trench or excavation






38. The form of the land. Contour lines are map lines connecting points of the same ground elevation and are used to depict and measure slope and drainage. Spot elevations are points of a specific elevation.






39. An unstable condition of a solution (water) in which the solution contains a substance at a concentration greater than the saturation concentration for the substance.






40. The force that resists the separation of two bodies in contact.






41. A reservoir for the storage of filtered water of sufficient capacity to prevent the need to vary the filtration rate with variations in demand. Also used to provide chlorine contact time for disinfection.






42. The height to which something is elevated - such as the height above sea level.






43. A U.S. government agency charged with administering vast areas of public land.






44. This landscape architecture specialization has evolved to encompass maintenance of a site in its present condition; conservation of a site as part of a larger area of historic importance; restoration of a site to a given date or quality; renovation o






45. Solid material settled from suspension in a liquid.






46. The conversion of large solid particles of sludge into very fine particles which either dissolve or remain suspended in wastewater.






47. In landscape architecture - a study of the potential cost of site purchase - demolition and improvement in comparison to the income or other benefit to be derived from site development.






48. A relatively clear or forested area left untouched in or near a city. It may be active open space - such as a baseball field - or passive open space - such as an area of natural woodland.






49. Narrowly defined - the amount of countryside and/or city that can be taken in at a glance. Also - an area of land or water taken in the aggregate.






50. Sewers are surcharged when the supply of water to be carried is greater than the capacity of the pipes to carry the flow. The surface of the wastewater in manholes rises above the top of the sewer pipe - and the sewer is under pressure or a head - ra
