Difference between throttle governing and nozzle governing

Question

Accepted Answer

Throttle governing controls flow rate by adjusting the size of the opening, while nozzle governing controls flow rate by changing the pressure at the nozzle outlet.

Throttle governing involves adjusting the size of the opening through which the fluid flows, controlling the flow rate.
Nozzle governing involves changing the pressure at the nozzle outlet to control the flow rate.
Throttle governing is commonly used in carburetors of internal combustion engines.
Nozzle governing is commonly used in fuel injectors of engines.
Throttle governing is more suitable for applications where precise control over flow rate is required.
Nozzle governing is more suitable for applications where pressure control at the outlet is critical.
