They need no additional bracing.
Heat transfer is the exchange of:
Mass between systems.
Thermal energy between systems.
Kinetic energy within a single system.
Potential energy between systems.
Heat always flows from:
Cold to hot regions.
High pressure to low pressure.
High temperature to low temperature.
Low density to high density.
Which is NOT a fundamental mode of heat transfer?
Conduction
Convection
Radiation
Diffusion
Thermal equilibrium is reached when:
All bodies are at absolute zero.
All bodies are at different temperatures.
All bodies are at the same temperature.
Heat transfer has stopped completely.
An example of desirable heat transfer in building design is:
Passive solar heating using thermal mass.
Heat gain from poorly sealed windows.
Air conditioning malfunction.
Heat loss through poorly insulated walls.
Heat loss typically occurs:
During the summer months.
When outside temperature is higher than inside temperature.
When outside temperature is lower than inside temperature.
When there is no wind.
The primary goal of heating system design is to:
Maximize heat loss.
Provide at least as much thermal energy as is lost.
Minimize the use of insulation.
Ignore heat transfer considerations.
Minimizing heat loss typically involves:
Increasing air leaks.
Using materials with lower R-values.
Using materials with higher R-values.
Ignoring insulation.
The goal of cooling system design is to:
Maximize heat gain.
Remove at least as much thermal energy as is added.
Minimize the use of insulation.
Ignore heat transfer considerations.
A significant source of heat gain in a building is:
Only occupant heat.
Only solar radiation.
Solar radiation and occupant heat.
Solar radiation, occupant heat, and equipment heat.
A BTU is defined as:
A unit of power.
The amount of heat required to raise one pound of water by one degree Fahrenheit.
The amount of energy in a kilowatt-hour.
A unit of electrical resistance.
Btu/h is a measure of:
Thermal resistance.
Thermal conductivity.
Heating or cooling power per hour.
Electrical current.
Approximately, how many BTUs equal one watt?
0.2931
3.21
3.4
12,000
12,000 Btu/h is referred to as:
A kilowatt.
A ton of cooling.
A BTU.
A watt.
R-value measures:
Thermal conductivity.
Thermal transmittance.
Thermal resistance.
Heat flow.
U-factor measures:
Thermal resistance.
Thermal conductivity.
Thermal transmittance.
Heat capacity.
The relationship between R-value and U-factor is:
R = U
R = 1/U
U = 1/R
R = U²
The outside air film's R-value is often neglected because:
It is too difficult to measure.
It is insignificant compared to other R-values.
It varies too much with weather conditions.
It is always zero.
The formula for calculating total heat loss is:
Q = A / (U * ΔT)
Q = A * U * ΔT
Q = U / (A * ΔT)
Q = ΔT/(A * U)
To calculate a wall assembly’s total R-value you:
Divide individual R-values.
Subtract individual R-values.
Multiply individual R-values.
Add individual R-values.
