Rig management system for transmission control of a hydraulic fracturing rig

A rig management system, comprising:

• one or more memories;
• and
• one or more processors, communicatively coupled to the one or more memories, configured to:
• receive pump control information associated with controlling a pump of a hydraulic fracturing rig;
• determine a modified flow rate to be used in association with the pump of the hydraulic fracturing rig based on the pump control information or a cavitation prediction map,
• wherein the cavitation prediction map identifies a respective modified flow rate for different combinations of inlet pressures and fluid properties of a fluid to be used with the hydraulic fracturing rig;
• determine an output torque of a transmission of the hydraulic fracturing rig based on the modified flow rate;
• determine a transmission gear for the transmission based on the output torque and a fuel consumption map,
• wherein the fuel consumption map identifies a respective fuel consumption rate for different combinations of transmission gears and output torques;
• and
• cause the transmission to shift into the transmission gear after determining the transmission gear.
