Table of power required to operate high-grade triplex pumps 



The estimates given in the table are made with a liberal allowance of power. 

 The power for other capacities and heights is, approximately, in proportion to 

 that tabulated. By " head " is meant the vertical distance from surface of water 

 supply to point of delivery. One foot head is equivalent to .43 pound pressure. 

 The head is increased by the friction of the water in pipes and elbows.
