Consider the following statements for the pneumatic and hydraulic systems: 1. The normal operating pressure of pneumatic control is very much higher than that of hydraulic control. 2. In, pneumatic control external leakage is permissible to a certain extent, but there should no leakage in a hydraulic control. Which of the statements given above is/are correct?

Correct Answer: Both 1 and 2
Operating pressure of pneumatic as the control,action is mainly to control the flow of air is more and also no leakage is permitted in hydraulic systems.
