2. Net power is. a useful power that is transmitted from pump to liquid a power transmitted by the engine to the pump an energy of pumped liquid a power on the pump shaft

The correct answer is: a power transmitted by the engine to the pump.<br /><br />Net power refers to the useful power output of a system, such as an engine or pump, after accounting for all losses, such as friction, heat dissipation, and other inefficiencies. In the context of a pump, net power is the power transmitted by the engine to the pump, which is the useful power that the pump can provide to the liquid being pumped.
