Why are baffles used in a shell-and-tube heat exchanger, for cooling hydraulic fluid?

(a) To provide structural support for the tubes,

(b) To circulate hydraulic fluid more effectively around the tubes, or

(c) To create a pressure drop across the heat exchanger.

What is the desired steady-state operating temperature for fluid within the reservoir of a hydraulic control system?

(a) Less than 60∘C,

(b) Less than 100∘C, or

(c) Less than 120∘C.
