somewhat . You correctly answered: constricted, dilated. 3 When you increased the ﬂow tube radius, the ﬂuid ﬂow rate You correctly answered: increased. 4 Explain how the body establishes a pressure gradient for ﬂuid ﬂow. Your answer: By heart construction, the pressure gradient is established. 1 Explain the effect that the ﬂow tube radius change had on ﬂow rate. How well did the results compare with your prediction? Your answer: The ﬂow tube radius increased the ﬂow rate, as I predicted. 2 Describe the effect that radius changes have on the laminar ﬂow of a ﬂuid. Your answer: When radius increased, ﬂow of a ﬂuid get more free to ﬂow than when radius is lower. The other way, when radius is narrow the ﬂow of a ﬂuid is restricted that rate as low. 3 Why do you think the plot was not linear? (Hint: look at the relationship of the variables in the equation). How well did the results compare with your prediction? Your answer: In graph, line is not straight, because radius and ﬂow rate have not just simple proportion. Flow rate have proportion with the fourth power of radius. 4
