Extracted text: 1. The choice of a taller tower generally results in higher energy yield. Determine the number of years it takes to offset the cost differential of choosing a taller tower based on the two scenarios described below: а. Dollar value of 1.0 kWh of electricity set at $0.065 and constant over the period necessary for computations b. i. Dollar value of 1.0 kWh of electricity set at $0.065 at the start, and increasing by 6% annually ii. The additional capital subject to 2.5% interest. Use the Simple Methods discussed in class for modeling the effects of height on changes in wind speed. Generator 10 kW Rotor diameter 7.0 m Hub height/standard Hub height/desired Average wind speeds of the site Air density Overall efficiency 100.0 ft 150.0 ft 5.4 m/s (at 100.0 ft) 1.2 kg/m3 0.35 (assume constant) Surface roughness coefficient 0.1 The total cost of the tower for units 100 ft tall or higher can be estimated by: Total tower cost = $2,500.00 +h? x $0.30 Where, h denotes the tower height in ft. List any further assumptions you make. Payback period: The number of years that it will take the taller tower to offset the extra cost by the Figher energy vield. with CamScann
