Design Master Divider Valve —
List design volume for groups1.
Design master divider valve — consider each secondary 2.
divider valve as a point, with the total design volume required
equal to the total of all points served by the secondary divider
valves.

Figure 7 Machine Bearing List
Given the above information, the next step is to design the secondary
divider valves.
Design Secondary Divider Valves —
Group 1 illustrates four single roller bearings (See Figure 7).1.
Group 2 illustrates five plain bearings (See Figure 7).2.
Group 3 thru 6 are not detailed; however total design volumes 3.
(cu.in./hr.) and MJ divider valves are shown.
Group 1 —
Single row roller bearings — Vol = D
2
R x T*
Group 2 —
Plain Bearings — Vol = π DL x T*
