Renewable Energy

Aim The aim of this experiment is to assess the wind characteristics of wind speed and direction at a site using instantaneous reading anemometers and a weather monitoring station.

Which renewable energy that has seen the most significant increase?(1%) a) Biomass b) Geothermal c) Solar d) Wind e) Hydropower

a) CC1 b) С2 с) ССЗ Which component class is considered fail-safe? (1%)

What is the equation of motion for a SDOF free vibration system? Define each term in the equation. (3%)

23. Figure below shows the surface wind velocity as a function of the natural log ofthe roughness length (Z). Plot a straight line and determine the roughness length(Zo) of the terrain if measurement points are: V1 = 2.5 m/s and V2 = 3.6 m/s.Steps: Plot V1 and V2 and determine LN(Z1) and LN(Z2) and use equation 15from lecture notes to get Zo.
