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.
Lifeboat may refer to: Lifeboat (shipboard), a small craft aboard a ship to allow for emergency escape. Lifeboat (rescue), a boat designed for sea rescues. Airborne lifeboat, an air-dropped boat used to save downed airmen.
What does R.M.S. mean, as in R.M.S. Titanic? Royal Mail Ship (sometimes Steam-ship, Steamer), usually seen in its abbreviated form RMS, is the ship prefix used for seagoing vessels that carry mail under contract to the British Royal Mail. The designation has been used since 1840[1].
