The flow is the same whether the system pressure is low or high, so long as the difference between the inlet and outlet pressures is the same. This equation shows the relationship: The water flow graphs (pages 8 and 9) show water flow as a function of pressure drop for a range of C v values.
The name Olmec means rubber people in Nahuatl, the language of the Aztec, and was the Aztec name for the people who lived in the Gulf Lowlands in the 15th and 16th centuries, some 2000 years after the Olmec culture died out.hey lived in the tropical lowlands of south-central Mexico, in the present-day states of Veracruz and Tabasco.
