the isochronous governors cannot be used when there are 2 or more units connected to the same system. since each generators whould have to have pricesely the same speed setting. otherwise they would fight each other, each trying to control system frequency to its own setting.

I saw one P&ID 6" control valve has been connected with 8" process line, and 2" valve also connected in parallel with 6" valve. why the 2" valve connected in parallel, Is there any technical reason. please clarify. With Regards-Kittu

How can we say that accuracy of measurement increases by using 3 or 4 wire RTD? because for example: If resistance of RTD element is say r ohms and Resistance of the cable from transmitter to RTD is R ohms And if 4 wire RTD is used, ____._____________________ R ohms | |_____._____________________ R ohms / \ / r ohms \ \ | |______.__________________ R Ohms | |_______._________________ R ohms Then the actual resistance measured will be: Total = r + R/2 + R/2 = r +R Ohms Note: r+R instead of r ohms. hence error
