The temperature at which this vaporization occurs will decrease as the pressure of the surrounding medium decreases.Technical Data and Pump Fundamentals TECHNICAL MANUAL TTECHWP.

Backing up to debug only private cacheWhere additional water is required for some special process, this should be added to pump capacity. Where laundries or swimming pools are to be supplied, add approximately 10 to pump capacity for either. Where the majority of occupants are women, add approximately 20 to pump capacity. Boiler Boiler Boiler Boiler Boiler HP GPM HP GPM HP GPM HP GPM HP GPM Boiler Horsepower equals 34.5 lb. F, and requires feed water at a rate of gpm. Select the boiler feed pump with a capacity of 2 to 3 times greater than the figures given above at a pressure 20 to 25 above that of boiler, because the table gives equivalents of boiler horsepower without reference to fluctuating demands.

Temperature, elevation and pressure can all affect drawdown volume. TABLE 2 PRESSURE FACTORS Pump Cut-Out Pressure PSIG Pump Cut-In Pressure PSIG To determine tank drawdown of operating pressure ranges other than those listed in table, use following procedure: Multiply total tank volume (table 1) by pressure factor (table 4). Percent of Tank Volume VERTICAL TANK TABLE Percent of Tank Height When using large standard galvanized tanks, a constant air cushion is required for proper operation of the water system. The illustrations show the percent of tank volume as related to the pressure gauge reading. To determine the amount of water you will receive as drawoff from the tank, you should subtract the smaller number from the larger number to get the percentage. Then multiply by the size of the tank to get the gallons drawoff. Example: 50 lbs. 77.3 minus 30 lbs. Based on an atmospheric pressure of 14.7 lb.sq.

Simply stated, it is an analysis of energy conditions on the suction side of a pump to determine if the liquid will vaporize at the lowest pressure point in the pump. The pressure which a liquid exerts on its surroundings is dependent upon its temperature. This pressure, called vapor pressure, is a unique characteristic of every fluid and increases with increasing temperature. When the vapor pressure within the fluid reaches the pressure of the surrounding medium, the fluid begins to vaporize or boil.
