Pipe or tube expansion can provide a flexibility to the longitudinal motion in a tall building
Which is NOT one of the main considerations for piping, tubing, fitting, and controls?
Easy maintenance
Minimum interference with architectural form and function
Thermal resistant
Corrosion
For heat conservation in the piping, which is NOT correct
How water carrying pipes should be insulated
Correct water temp at boiler
Hot and cold water pipe should be separated to prevent heat exchange
Storage tanks are usually manufactured with insulation
Considering liquid waste removal, which is correct?
A vertical drain pipe that collects waste from one or more fixtures is called a main stack
The main stack is generally 3" in diameter
All stacks extend into basement and empty into branch main
Gases from the system dissipate through the house drain
Most commonly used trap type with plumbing fixtures is p trap
True
False
Traps are required because they prevent water from entering a building and causing serious illness or death
True
False
The term trap seal refers to the water being held in the bent portion of a fixture trap
True
False
The trap seal forms a seal agains the passage fo sewer gases through the trap and into the building
True
False
A plumbing _______ is designed to help clearing any type of debris that could cause any type of stoppage in the water drain lines
____ is a diagrammatic drawing to show the plumbing plan by using symbols of piping and fittings, It is used as supplementary details on working drawings in order to show clearly how the plumbing system is to be installed
Which is not correct about the plumbing plan?
The plumbing plan is a plan view that shows the complete plumbing system
The plumbing plan shows the location, size, and type of all plumbing equipment
The plumbing plan should include waste lines and vent stacks
A plumbing plan is required for generic form only
Which building certification system is the oldest one?
GBCA
CASBEE
LEED
BREEAM
Which is not correct about septic tanks?
Septic tank is a primary treatment
The longer stay in the septic tank guarantees the less polluted effluent
Generally it is made of precast concrete
Only 30% of liquid waste is purified after septic tank
What is the latest version of the IBC
2018
2021
2020
2015
Building classification: office, professional, and service activities
Building classification: space used for K-12 education
Building classification: spaced using low- hazard, non-flammable materials
Building classification: Spaced used for education above k-12
Lighter structures, light gauge steel. etc
Type III
HT
In general, if construction type changes from type I to type IV, occupancy and cost
Regarding water recycling, which is not correct
Today, graywater and blackwater are mixed and rainwater is collected separately
Filtering of graywater is unnecessary for irrigation purposes
Common usage of graywater in residential building are water closet, low flush water closet, and irrigation
Blackwater needs intensive treatment before usage
Regarding the tenability in the fire, which is not a major factor to consider?
Visibility
Airflow
Toxicity
Temperature
Considering the smoke control, which is not correct
In the tall building, the smoke spread pattern is simpler than the low building
In the low building the smoke is spread by the heat-induced convective air motion
Tall building creates stack effect for smoke movement
The heat produces air pressure and buoyancy that spreads the smoke
Which is not a smoke compartmentation strategy
Firewalls
Curtain boards
Move the heat and smoke to the other space by using the fan
Initiate detection and suppression system
Compartmentation loses its effectiveness once smoke got thicker
True
False
Typical fire barrier works well to prevent spreading the smoke
True
False
Confinement strategy must be combined with detection/suppression system
True
False
Visual inspection, blower door test, and smoke pencils are common methods for passive systems testing
True
False
_____ is a strategy which dumps large quantities of outdoor air into a refuge area which creates pressurized space
Exhaust employ both air velocity and air pressure
True
False
For exhaust low velocity is used to mix the fresh air with the smoke
True
False
Exhaust is a useful smoke control strategy for small volume spaces
True
False
Exhaust system increases the initial cost
True
False
Regarding combined systems of hvac, fire detection/suppression and smoke exhaust system, and suppression, which is not correct?
The combined system will pressurize the HVAC zone to create a barrier
The combined system must keep the smoke out of return air duct
The combined system should use the return air and block the outdoor air
Once the combined system is initiated, it should override the conventional HVAC
Considering the fire suppression, water is the readily available and relatively low cost
True
False
As a fire suppression medium, water removes 970 btu/lb from the fire
True
False
Water can be used to suppress fire triggered by oils
True
False
Considering the fire suppression, water can damage the office appliances by conducting the electricity
True
False
Which is not correct choose two
Class II standpipes and hoses are used once the fire truck arrives
Class I standpipes and hoses are for full scale fire fighting
All sprinklers will be activated at the same time
The pipes are filled with water in general wet systems
Smoke will not activate the sprinkler
The minimum distance between the sprinkler head and the top of the indoor space contents should be _____ inch
Quick response sprinklers are the recommendation for the light hazard occupancies
True
False
Quick response sprinklers use smaller mass in the glass bulb which initiate the system early
True
False
ESFR sprinklers operate at low pressure and flow
True
False
Extended coverage sprinklers are limited to the unobstructed construction type
True
False
Regarding the sprinkler system for most general buildings, _____ is the most common and simplest system which filled with water under pressure
Regarding the sprinkler system for most general buildings, _____ is filled with compressed air and used in an unheated area
