At a hydroelectric power station, a turbine is located $30\,\text{m}$ beneath the surface of a large lake. Water flows through the turbine at a rate of $340\,\text{m}^3$ per minute. The turbine and generator system has an overall efficiency of $90\%$. Determine the output power of the power station. (The density of water is $1000\,\text{kg m}^{-3}$.)
- A$0.15\,\text{MW}$
- B$1.5\,\text{MW}$
- C$1.7\,\text{MW}$
- D$90\,\text{MW}$
