Dear All

May I know, What the differences between Fan static pressure (FSP) and Fan Total pressure (FTP) in Local exhaust ventilation (LEV) system? Which value that rotate the fan in pump system either FTP or FSP?

In determine the value of brake horse power (BHP), we only just use FTP value as formula below

BHP= ( QXFTP)/(6356XME )

Thanks in advance
