DIFFERENCE BETWEEN TOTAL DYNAMIC HEAD AND DIFFERENTIAL PRESSURE

[gorkus]

P.D pump.
Total dynamic head = total suction lift + total discharge
head ( feet of liquid)
and the differential pressure is the same value but in psi
is Ok?

thank you

 

[sailoday28]

TDH= discharge (pressure/density +elevation+v^2/2)-
suction( (pressure/density +elevation+v^2/2)

Units are generally in feet or meters but could be converted to psi or Pascals

differential pressure as stated is the difference in pressure but could be stated in ft or meters.
