HW3 is to create a precedence diagram for the 11 activities shown in the "Activity Listing" tab in the attached Excel spreadsheet.

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. (5%)

3. (10%) A 12-V battery is connected across a device whose resistance is 30 ohms. Calculate the current in the wire. What is the power dissipated by this load?

An electric power distributor charges residential customers $0.15 per kilowatt-hour (kWh). The company advertises that "green power" is available in 150 kWh blocks for an additional $5 per month. (Green power is generated from solar, wind power, and methane sources.) a. If a certain customer uses an average of 480 kWh per month and commits to one monthly 150 kWh block of green power, what is her annual power bill? b. What is the average cost per kWh with green power during the year? c. Why does green power cost more than conventional power?

For the basic parameters for Wind Turbine Classes, CC1 refers to: (1%) a) Load bearing structural components that when failed would result in major failure of wind turbine. b) Load bearing structural components that when failed would not result in major failure of wind turbine. c) Mechanical components that attached to the main structure.
