Niagara Falls is about 50 m high. a. What is the temperature rise in kelvins of the water from just before it goes over the cliff to just after it hits the rocks at the bottom of the falls, assuming negligible air resistance during the fall and that the water doesn't rebound but just splats onto a rock? It is helpful (but not essential) to consider a 1 g drop of water. b. In the Niagara Falls hydroelectric generating plant, the energy of falling water is converted into electricity. Assuming that the energy conversion is highly efficient, approximately how much energy is obtained from one kilogram of falling water? Approximately how many kilograms of water must go through the generators every second to produce a megawatt of power (1 x 106 W)?

Patm 1. Initially; the piston sits on the stops and the linear spring exerts no force, the specific volume is 0.05 m /kg and the pressure is 125 kPa. Atmospheric pressure is 100 kPa, mass of the piston is 102 kg, and area of the piston is 200 cm?. The linear spring exerts a force on the piston in such a way that the specific volume becomes 0.08 m'/kg when the pressure reaches 200 kPa. Heat is transferred to the water until its temperature is 115 °C. Calculate work and heat transfer, showing the process on a P-v plot. Hint: In the final stage, the temperature is 115°C, but the pressure is not given. You need to find P and v using the tables and P-v plot.
