A turbine in a hydroelectric power station lies $30\,\text{m}$ beneath the surface of a large lake. Water flows through the turbine at a rate of $340\,\text{m}^3$ each minute. The combined efficiency of the turbine and generator system is $90\%$. Calculate the power output of the station. (The density of water is $1000\,\text{kg m}^{-3}$.)
