Peak demand can vary greatly based on the number of simultaneous water uses, the flow rates of individual water fixtures, and the length of time fixtures operate. 5 gpm (two fixtures running simultaneously at 2.5 gpm) is a good estimate of peak demand, for the typical household. Water wells that reliably yield 5 gpm should be able to meet peak and daily needs for most residences. Wells yielding less than 5 gpm, however, are sometimes the only water source available.

Lifeboats, Lifeboat Equipment and Rafts. [As taught to U.S. Maritime Service Trainees in World War II] All articles of equipment for lifeboats must be of good quality, efficient for the purpose they are intended to serve and kept in good condition. Lifeboats must be fully equipped before the vessel leaves port, and the equipment must remain in the boat throughout the voyage.
