TPC 102 Flashcards
(50 cards)
A SCHEMATIC IS MADE UP OF
SYMBOLS AND LINES
DOUBLE LINE DRAWINGS THAT SHOW THE INTERNAL DETAILS OF A PNEUMATIC SYSTEM ARE CALLED
CUTAWAY DRAWINGS
IN A DC CIRCUIT THE ELECTRONS FLOW FROM
ONE DIRECTION ONLY
ARROWS ARE USED ON PIPING DIAGRAMS TO INDICATE THE
DIRECTION OF FLOW
IN A PIPING SYSTEM AN ALTERNATE FLOW PATTERN IS INDICATED BY A
SUPPLEMENTARY DIAGRAM
ON AN ELECTRICAL DIAGRAM A DASHED LINE INDICATES
EXPOSED WIRE
VENT LINES AND DRAIN LINES ARE SHOWN ON A HYDRAULIC SCHEMATIC BY
DASHED LINES
IF A SCHEMATIC CARRIES NO LEGEND CLUES ABOUT IT MAY BE FOUND IN THE PARTS LIST DRAWING TITLE AND
ENGINEERS NOTES
