IOP for relay pumping
130
simplest method for relay pumping
constant pressure method
minimum psi reading on intake gauge for relay pumping
20 PSI
main reason for the use of water
heat absorption
Types of pressure and their definition.
ATMOSPHERIC - 14.7 PSI AT SEA LEVEL (ALTITUDE)
HEAD - HEIGHT OF WATER (ELEVATION)
STATIC - STORED POTENTIAL ENERGY
NORMAL OPERATING - PRESSURE IN THE DISTRIBUTION SYSTEM DURING NORMAL HOURS
RESIDUAL - WHAT’S LEFT AFTER OVERCOMING FRICTION LOSS
FLOW - FORWARD VELOCITY PRESSURE
