The ratio for the cross section areas of the tube is A2

A1

= 0.535, the difference in the

pressures is P1 − P2 = dP = 29.9 Pa , and the

density of the fluid is 2.97 kg/m3

.

Find the speed of the fluid near the right

hand end of the tube (i. e., find v2).

Answer in units of m/s.

7. see worksheet 1 for values of variables x1, x2 and x3 and answer the following questions: a. for each variable find the mean, median, coefficient of skewness, range and population standard deviation. b. compared to variable x1, how are the mean and median affected by extreme values (outliers) seen in x2 and x3. c. is the median or mean the better measure of location for x2 and x3? explain. d. explain the differences in the magnitudes of the skewness coefficients for the three variables. e. what is the relationship between the range and standard deviation looking across the three variables?
