DP = P1 - P2

Where:

DP = Differential pressure

P1 = one pressure

P2 = the other pressure.

To say any more we would need more information.

Please register & re-state your problem.

Fisher Controls publishes charts about Pressure Gradients for processes on a regular basis. They include pressures from source to return lines (recirculation) and so on. One way that I did it is by tapping in on a flow line across the OP. At the time there was no DP Cell installed and we wanted to know what the pressures were. After getting the P1 and P2 we coverted the resultant Pƒ to inches of water and there we had our calibration parameter.

DP across what ( a filter ? orifice ? pump? compressor? ???????????)

The question is too vague and inadequate for giving any intelligent reply.

DP = Ex-wife (P1) meets new girlfriend (P2) at mutual friend's party

Therefore we have DP = P1-P2 resulting in a force difference that causes migration of P2 away from P1 to the distance where DP equalises (about 712 km).

It sounds as though uninstalling Wife 1.0 would solve the problem.

I did un-install but just like Microsoft there are still pieces left all over here and there that contaminate all other applications and cause them to not function . . . randomly and for no apparent reason and it can't be fixed without moving to the southern hemisphere.
