    Abstract: A system includes a mud pump for pumping a drilling mud from a drilling mud source, through a drill string, out a drill bit and into an annular, and a plurality of chokes disposed down stream from the mud pump, including a first choke disposed between the mud pump and the drill string, and a second choke disposed between the mud pump and a mud tank. The system further includes a fluid discharge conduit in fluid communication with the annular space for transferring the drilling mud to handling equipment in fluid communication with the mud tank. The first choke receives the drilling mud from the mud pump at a first flow rate, the first choke reduces drilling mud flow rate to a second flow rate less than the first flow rate, and the second choke reduces drilling mud flow rate to a third flow rate.
