100%
The diameter of a pipe changes gradually from 6 inches at A to 18
inches at B. A is 15 ft lower than B. If the pressure at A is 10 lbs per
square inch and at B, 7 lbs per square inch when there are 5.0 cubic ft
per second flowing, determine:
a. the direction of flow.
b. the frictional loss between the two points
B. If in Problem 1 the direction of flow is reversed, determine the
pressure at A if all other factors, including the frictional loss, remain the
same.
C. In Problem 1, determine the diameter of pipe at B in order that the
pressure at that point will also be 10 lbs per square inch, all other
factors remaining constant.
D. Determine the discharge in Problem 1, assuming no frictional loss, all
other conditions remaining as stated.
E. What would be the difference in pressure in pounds per square inch
between A and B, Problem 1, if there were 6.2 cubic ft per second
flowing, neglecting friction.
