You Can Do Thermodynamics: Hydroelectric Plant Powering a 150-Watt Light Bulb. Water Flow Needed?

This is an educational Thermodynamics video showing how to solve for the needed amount of mass flow of water to be fed into a hydroelectric plant to be able to power a 150-Watt Light Bulb. After the mass flow of water is solved for units is solved for in units of kilograms per second, the volumetric flow of water is determined in units of gallons per minute. Efficiency and Loss of Transmission are taken into consideration for this Thermodynamics problem.
