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.
For other meanings, see Bow (disambiguation). Bow of the Cruise ship Spirit of Endeavour. The bows of lifeboat 17-31 (Severn class) in Poole Harbour, Dorset, England. The bow is the forward part of the hull of a ship or boat, the point that is most forward when the vessel is underway. The bow is designed to reduce the resistance of the hull cutting through water and should be tall enough to prevent water from easily washing over the top of it.
