2. Net power is defined as (where rho is density, g- gravity acceleration, Q -volumetric discharge, H- head of the pump: N_(net)=rho gQP N_(net)=rho gQH N_(net)=QH N_(net)=rho gH

The correct answer is: $N_{net}=\rho gQH$<br /><br />Explanation: Net power is defined as the power output of a pump or turbine, which is the product of the density of the fluid ($\rho$), the acceleration due to gravity ($g$), the volumetric discharge of the fluid ($Q$), and the head of the pump ($H$). Therefore, the correct formula for net power is $N_{net}=\rho gQH$.
