Refer to the drawing of an operating cooling water system (see figure below) in which valves A and B are identical.
Valve A is one-half open and valve B is fully open.
If valve A is opened fully, the differential pressure (D/P) across valve B will…
A. increase by the same amount as the absolute change in D/P across valve A.
B. increase by an amount less than the absolute change in D/P across valve A.
C. decrease by the same amount as the absolute change in D/P across valve A.
D. decrease by an amount less than the absolute change in D/P across valve A.
