In thermofluids problem-solving, what is the main purpose of checking whether an answer is physically reasonable?
Question 2
A flow rate is calculated as $-2\,\text{kg/s}$. What is the most appropriate physical interpretation?
Question 3
Why is it important to compare a thermofluids result with limiting cases, such as very large or very small values of a parameter?
Question 4
A computed temperature is $450\,\text{K}$ for air in a room that is known to be near $300\,\text{K}$. What is the best next step in interpreting the result physically?
Question 5
What does a dimensionless quantity being very close to zero often suggest in physical interpretation?
