Estimating Evaporation from Water Surfaces

2011-10-25 · stored energy gradually becomes available for evaporation and sensible heat loss. For shallow water bodies, the amount of energy stored during the rising and falling solar cycle may not be large, but usually is large enough to affect daily evaporation rates. The fraction of daily solar radiation that is reflected from water surfaces (albedo) during

Boiler Ratings and Boiler Load - Alken-Murray

2007-3-24 · Boiler Ratings and Boiler Load . The oldest method of rating boilers, still used to rate small boilers, is by horsepower (hp). One horsepower is defined as the ability to evaporate 34.5 lbs of water into steam at 212 deg. F and above. Large boiler capacity is generally given in lbs of steam evaporated per hour, under specified steam conditions.
