a Calculate thc amount of wind energy at 15°C and 1 atm prcssurc that passes through 1 m? of cross- sectional area for the following wind regimes: Regime 1: 100 h of 6 m/s winds Regime 2: 50 h at 3 m/s plus 50 h at 9 m/s What is the ratio of Regime 1/Regime 2 in % ? a) 57.14% b) 59.26% c) 100% d) 67.23% e) 47.45% b. Identify the "TRUE" statement: a) A smaller generator and faster rotor speed are more effective in higher wind speeds. b) Power curve is proportional to the square of wind speed c) Torque versus turbine speed trajectory follows a cube law. d) In the design/selection of a wind turbine system, keeping the same rotor but increasing the generator size allows the power curve to continue downward to the new rated power. e) Using brushless synchronous generators in wind turbine can be expensive since power electronics rating equals to output power rating. f) Off-shore wind farm applications, the clusters of turbines are usually positioned in irregular row and column structure.

A Printed Circuit Board (PCB) machine installs integrated circuits onto a board. Before starting to produce a board, the PCB machine requires a 25-minute setup. Once in production, the PCB machine requires only 0.16 minute per board. a. (Do not round intermediate calculations. Round your answer to 2 decimal places.) Currently, the PCB machine produces 600 boards between setups. Given this operating process, what is the capacity of the PCB machine (in boards per minute)? (Do not round intermediate calculations. Round your percentage answer to 2 decimal places.) Currently, the PCB machine produces 600 boards between setups. Given this operating process, what is the utilization of the PCB machine? b. Say the PCB machine produces 400 boards between setups and demand is 3 boards per c. minute. Given this operating process, what is the average inventory of boards at the PCB machine? (Round your final answer to 2 decimal places.) d. Demand for boards occurs at the rate of 3 boards per minute.…
