The 32-in pump is to pump 24,000 gal/min of water at 1170 r/min from reservoir whose surface is at 14.7 lbf/in2 absolute. If head loss from reservoir to pump inlet is 6 ft, where should the pump inlet be placed to avoid cavitation for water at (a) 60oF, pv

line ED

Step-by-step explanation:

Let analyse all possible

a. line CD

From the photo, you can see it lies on the plane A and only point D is either on plane A or B.

b. line ED

From the photo, you can see the point E and D are lying on plane A and B.

c. point C

Only in plane A

d. point D

point D is on plane A or B.

However, to describes the intersection of 2 planes, we usually use the a line or a segment to have a better explanation because it goes through all the common points of the two planes
