pressure due to elevation change
PRESSURE VARIATION:
Sideroll Headloss (19) + Elev pressure Gain/Loss (20)
(DP)
x 100
PRESSURE VARIATION MUST NOT EXCEED +/ -10% OF DP. If flow control nozzles are
used, then + / -10% pressure limit can be dealt with easily.
REQUIRED PRESSURE AT MAINLINE AT BEGINNING OF SIDEROLL (MPS)
