How far can a fire truck draft water? Although the theoretical lift of 33.8 feet is exceeded in practice, the highest height to which water may be drawn is more in the range of 20-25 feet.
WebbStandard atmospheric pressure is 101 kPa (14.7 lbf/in²) and that can only raise water to a theoretical maximum of 10.3 metres (33.9 ft). Depending on application, fire department pumps lift water 6 to 10 metres (20 to 30 ft). To reduce drafting friction and obtain a larger flow or higher lift, a larger cross-section of suction hose is employed. WebbTheoretical lift: scientific height that a column of water may be lifted by atmospheric pressure in a true vacuum; at sea level, this height is 33.9 ft. the height will decrease as …
WebbWhen drafting water, the air at atmospheric pressure is removed from the hose line, creating a vacuum (negative pressure) within the pump chamber. The atmospheric pressure (weight of air) on the water's surface forces the water up through the suction … WebbTHEORETICAL LIFT CAN BE CALCULATED BY DETERMINING THE ATCUAL ATMOSPHERIC PRESSURE OF AN AREA AND: MULTIPLYING THAT NUMBER BY THE WATER'S …
WebbThe formula for determining the maximum lift a pumper can achieve: Lift = 1.13 x Hg Determine the maximum height to which water will be lifted when intake guage reads 14 …
WebbA strainer is submerged at least two feet in a water depth of at least four feet. As the lift or friction loss in hard intake hose is increased, the water supply capability of the pump decreases. The pump may only deliver about 70% of its capacity if lift is increased by 5 feet, to a 15 foot lift, and 60% at a 20 foot lift.
