본문내용
1. In Chapter 5, we solved the below problem to determine the thrust force F. This is also one of the internal flow problem. What is the major difference between the analysis in Chapter 5 and that in Chapter 8. (4 marks)
2. Water at a temperature of 10oC flows through a pipe of diameter D=1.85 cm and into a glass as shown in the figure. We like to determine the time to fill the glass with water if the flow is to be laminar. (4 marks)
This is the question.
What kind of time can we determine, the minimum time or the maximum time? (2 marks, if wrong –2 marks) And why is that? (3 marks)
3. For the internal flow, the critical Reynolds Number is known as, (4 marks)
Re < 2,100, laminar
Re > 4,800, turbulent
Why de we need to know this critical number?
4. Let’s consider the fully developed laminar flow case as below. (4 marks)
We tried to find the solution for that flow problem.
From the solution, we are able to find the answer for the following question.
