Summary

Static pressure of a water column against height, about 9.8 kPa per metre; the marker shows the worked example at 300 ft (91.4 m). Friction losses and the outlet pressure come on top. Based on Titus (2002), p. 4-45.

Original vector illustration for Dry and wet risers, level 2 Intermediate.

Source basis: Titus (2002), p. 4-45 (fluid statics, 0.433 psi per ft of head); Razza and Grill (2005c), p. 48 (automatic fire pump only for the lower 300 ft); Hopkins et al. (2005), p. 20 (100 psi at the remote outlet)
Alt text: Straight line of static pressure against height, rising about 9.8 kPa per metre, with a marker at 91.4 m and 897 kPa.
