DIFFERENCE BETWEEN TOTAL DYNAMIC HEAD AND DIFFERENTIAL PRESSURE

DIFFERENCE BETWEEN TOTAL DYNAMIC HEAD AND DIFFERENTIAL PRESSURE

DIFFERENCE BETWEEN TOTAL DYNAMIC HEAD AND DIFFERENTIAL PRESSURE

(OP)
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

RE: DIFFERENCE BETWEEN TOTAL DYNAMIC HEAD AND DIFFERENTIAL PRESSURE

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.
