Compute the energy per unit mass that could be obtained by letting the water flow over a 110m dam. Cv=4.2kJ/kg/degrees celsius

Herbert, unfortunately that's not how things work here.

If you've got a homework question, you should post it in the appropriate forum along with your attempted solution.

People here aren't generally willing to do other peoples' homework for them, sorry.

Thread moved to Intro Physics. As brewnog says, herbert, you must show us your attempt at solving the problem before we can offer you tutorial help.

What can you tell us about the equations of work and energy? How would you compute the potential energy involved with a 110m tall dam, and water moving from the top to the bottom of the dam?
