CASE HISTORY NO. 1 (4 describing CORAVOL
results In'
steam systems
OPERATING CONDITIONS i
Winter months--Averoge per month. . Evaporation -- 8,098,000 lbs. Make-up -- 34,103 gal. Degree doys -- 1,296
PROBLEM: ^
Corrosion In steam and return lines. Pitting of racelvrng tanks. Rust deposits interfered with operation
of traps and vacuum pumps.
CORAVOL STARTED: September 1939.
RESULTS:
Corrosion stopped. No further deterioration of lines and receiving tonk. Traps operate perfectly. All rust deposits removed.
Bureau of Mines Gives! Shale Oil for Research

"Pipe pounding and heating complaints have been
eliminated. The receiving tank has not been blown down for over a yeor and the water In it remains as clear as crystal,"

CORAVOL In your sleom system (1) prevents cor rosion in lines, (2) cleans out dogging rust deposits. Thus, CORAVOL protects fines; Improves heat trans fer; restores original capacity of lines and efficiency of valves and traps.
CORAVOL h not o boiler feed water treatment--It Is designed expressly for use In steam systems. Because
CORAVOL volatilises and condenses with the steam. It circulates throughout your entire steam system and protects all zones from corrosive ottock.

Pointerson Pumps
HOW IS "HEAD" CALCULATED?
The total head of a centrifugal pump is the energy it imparts to the liquid, end is deter* mined by finding the difference between dis charge head and suction head. Thus, as a suction lift is a negative suction head, the total head is the sum of the discharge head and the suction lift.
If the discharge head and the suction head are not determined independently, the total head can be calculated by determining the algebraic sum of (0 'he static head from supply level to discharge level,(2) sit fric tion losses for the capacity considered, (>) entrance and exit losses and, (4) terminal pressure minus suction supply pressure. For complex systems involving both vacuums and pressures it is often easier to cooverc these factors into absolute pressure values, expressed in feet of the liquid handled.
When measured by gages at the pump's suction and discharge opening, the total head is rhe discharge bead minus rhe suction head. Discharge head is the sum-of the dis charge gage reading, corrected to the pump center line, and the velocity head at the point of the gage's attachment. Suction head is found by applying the ume formula to the suction gage reading. Since it is easy to get the plus and minus signs of the various ele ments reversed, and because of the many pre cautions necessary in taking gsge readings, it is advisable to follow the instructions in the Test Code of tbe Hydraulic Institute.
Tbe diagram shows the heads involved la calculating suction head, discharge head, total head and NPSH. (The term "NPSH" was discussed in a previous advertisement in this series. Reprints jre available on request.)
