WebTotal Discharge Head (hd): It is the sum total of discharge reservoir pressure head (hpd), static discharge head (hd), the velocity head at the pump discharge flange (hvd) and the total friction head in the discharge line (hfd). hd = hpd + hd + hvd + hfd. Manometric head: It is defined as the head against which a centrifugal pump has to work ... Web3. Static Head (H s): The sum of suction head and delivery head is known as static head. This is represented by ‘H s’ and is written as Hs= h s + h d 4. Manometric head (H m): The manometric head is defined as the head against which a centrifugal pump has to work. It id de-noted by ‘H m’. It is given by the following expressions: (a) H ... login to sgx
