Study Notes
Hydrostatic Head Calculations
- The relationship between inches of water column (w.c.) and pounds per square inch (psi) : 27.7 in w.c. = 1 psi
- Formula for calculating pressure (P) in psi: P = 0.433 x SG x H
- SG = Specific Gravity
- H = Head in inches
- Actual inches level multiplied by SG equals inches of water column (in w.c.)
- The table shows various levels, pressures in inches w.c., specific gravity (SG), and calculated pressures in psi.
- To calculate the pressure in psi, use the formula above
- The first row's calculations are demonstrated:
- Level: 126 inches
- Specific Gravity: 1.09
- Pressure in in w.c.: 38.5
- Pressure in psi: 5
- Calculation: 0.433 x 1.09 x 38.5 = 5 psi
- The second row is an outlier due to the incorrect pressure calculation.
- All other rows show correct pressure calculations for the given level, specific gravity, and formula.
