Study Notes
Calculating Height (Level)
- The formula for calculating height (level) is: h = P / SG
- h is the height of the liquid in inches or feet
- P is the head pressure in inches of water or psig
- SG is the specific gravity of the liquid
Calculating Head Pressure
- The formula for calculating head pressure is: P = h x SG
- P is the head pressure in inches of water or psig
- h is the height of the liquid in inches or feet
- SG is the specific gravity of the liquid
