Temperature Flashcards
What are the figures for absolute zero, freezing and boiling point of water in Celsius?
Absolute zero = -273
Freezing point = 0 (ISA conditions)
Boiling point = 0 (ISA conditions)
How do you convert between Celsius and kelvin?
c -> k = + 273
What is the freezing and boiling point of water in Fahrenheit?
Freezing = 32F
Boiling = 212F
How do you convert Celsius to Fahrenheit?
X 1.8 then + 32
What is OAT, SAT and TAT?
OAT = outside air temp measured at a point NOT in sunlight
SAT = static air temp, the inferred temperature outside an a/c for air NOT affected by movement
TAT = total air temp, sensed temperature outside an a/c affected by adiabatic heating as the air relative to the a/c is slowed to zero
What is ram rise?
The difference between SAT and TAT caused by adiabatic heating
SAT = TAT + ram rise
