find out whether this rule is valid or invalid.

The Confirmation Bias

 

Imagine that each square below represents a card. Suppose that you are participating in a study in which the experimenter tells you that every card has a letter on one side and a number on the other side.

You are then given this rule about these four cards: ‘‘IF A CARD HAS A VOWEL ON ONE SIDE, THEN IT HAS AN EVEN NUMBER ON THE OTHER SIDE.’’

Your task is to decide which card (or cards) you would need to turn over, so that you can find out whether this rule is valid or invalid. What is your answer? The correct answer is discussed later in the chapter.

(Incidentally, the answer to the problem about the objects on p. 415 is‘‘valid.’’)

Compare this result with the DU/Dt evaluated with that of the material time derivative and flux terms.

Figure P4.67 illustrates a system and fixed control volume at time t and the system at a short time δt later. The system temperature is T = 100 °F at….

Prepare a paper on your findings; be sure to include several pictures.

Flow visualization is direct observation of the flow field, usually accomplished in a laboratory. Several photographs in this book (see Figs. 3.1, 9.19, and 11.4) and the majority of the….
