Conversion factors
Flow rate
l/min ÷ 60 = l/sec
m3/hour ÷ 3.6 = l/sec
GPM ÷ 13.2 = l/sec
kg/sec = l/sec
Figures are given for clean cold water.
Pressure
m Hd ÷ 10.2 = bar
PSI ÷ 14.47 = bar
kPa ÷ 100 = bar
kg/cm2 ÷ 10.2 = bar
Figures are given for clean cold water.
Variable-speed flow, head and power calculations
Flow rate
Flow rate at reduced speed = (reduced speed ÷ full speed) X flow rate at full speed
Head
Head at reduced speed = (reduced speed ÷ full speed)2 X head at full speed
Power
Power at reduced speed = (reduced speed ÷ full speed)3 X power at full speed
