Hi ,
What is the total pump head in a closed loop? Apart from suction and discharge pressure what else will be considered ? Please explain total head.

Please clarify
1) total pressure= discharge pressure - suction pressure
2) if the above statement is true then, is pump head = total pressue?
Both are in a closed loop system.
