An installation consists of an electric motor which drives a water pump to lift$75 \mathrm{L}$of water per second to a height of$5\mathrm{ }\mathrm{m}$, where water is disbursed at negligible speed. If the motor consumes a power of$5 \mathrm{kW}$, then what is the efficiency (%) of the installation? [$\mathrm{g}=10 \mathrm{m} {\mathrm{s}}^{-2}$]
