EGR 102 Introduction to Engineering Modeling Lab 02B Homework You wish to predict the power and profit produced by a wind turbine. The efficiency of the wind turbine fluctuates based on the incoming wind speed, as shown below: Wind Speed (m/s) Efficiency 0 ≤ v < 5 18 % 5 ≤ v < 8 24 % 8 ≤ v < 13 32 % 13 ≤ v ≤ 15 12 % Build an Excel spreadsheet to calculate the power produced by this turbine. Create 16 cases by varying the wind speed from 0 to 15 m/s in 1 m/s increments. The power generated, P (kW) , may be calculated from the efficiency, E (in decimal form), the diameter of the turbine blades, D (m) , the density of the air, ρ (kg/m 3 ) , and the speed of the incoming wind, v (m/s) : ± ² ³ [ ´ µ ³ ¶ ·¸¸¸ ] ³ ¹ º ³ » Initially, use a turbine blade diameter of 20 m , and air density of 1.15 kg/m 3 . Also, calculate the monetary profit from selling the electricity over a 1-year period for each case. Assume a market rate of $0.09/kW-h of electricity (Hint: There are 8760 hours in
