A dam in western North Carolina takes a 30 m3 /s flow of water from the Nantahala river and diverts it to a turbine through a 2 m diameter pipe. The elevation drop from the inlet to the exit is 300m. Calculate the mass averaged velocity through the pipe, and estimate the power output of the turbine,assuming negligible changes in KE and temperature of the flow.
in a steam power plant the boiler output is at 800 f and 900 psia.a. if the turbine exhausts to a condenser at 10 psia
Determine the resultant of the three forces F1 = 2.0i + 3.3j - 2.6k; F2 = - i + 5.2j - 2.9k; and F3 = 8.3i - 6.6j + 5.8k, which are concurrent at the point (2, 2, -5.). The forces are in Newton's and the distances are in meters.
one pound mass of water in a piston-cylinder assembly initially a saturated liquid at 1 atm undergoes a
steam having pressure 4.0 mpa and temperature of 880 k enters the turbine installed in a power plant at the rate 500
