Silver Falls in the Green River Gorge has a sheer drop of 550 feet. Use the steady flow energy equation discussed in class to estimate the water temperature rise, in oF, resulting from the fall. Then estimate the temperature rise after the fall if the Silver River has a flow velocity of 15 feet per minute prior to the fall. Make any reasonable assumption, only if needed, to solve the problem. Please cite all sources of information.
A vertical piston-cylinder device, which is insulated, initially contains 15 kg of water, 9 kg of which is in the vapor phase. The pressure inside the cylinder is maintained constant at 0.3 MPa by mass of the piston. Now steam at 0.8 MPa and 500 °C i..
