Estimate the power available in a tidal stream flowing at 3m/s using a 5m diameter propeller turbine.© BrainMass Inc. brainmass.com October 24, 2018, 11:14 pm ad1c9bdddf
The power P generated by an ideal turbine (no losses) is given by:
P = (r * A * v^3)/2
r is the water density (1025 kg/m^3 for sea water)
A is the sweep area of the turbine (the area the propeller blades ...
The power is a propeller turbine in a tidal stream is determined in the solution.
What steps would you take to restore your community's economy and environment?
Assume that you are the mayor of a coastal town where some residents are employed as commercial fishers and others make a living serving ecotourists who come to snorkel and scuba-dive at the nearby coral reef.
In recent years, several fish stocks have crashed and ecotourism is dropping off as fish disappear from the increasingly degraded reef.
Scientists are urging you to help establish a marine reserve around portions of the reef, but most commercial and recreational fishers are opposed to this idea.
