4- Explain what is meant by TSR....and fill in the table. Tip-Speed Ratio 2 is the ratio of the speed of the rotating blade tip to the speed of the wind. If the TSR 2. is above 1, that means there is lift involved to make the blades spin faster than the wind speed. If the TSR is below 1, there is a lot of drag going on! Wind speed (Higher/Lower) Tip Speed(Higher/Lower) TSR More than 1 Equal to 1...

A turbine designer is trying to select the appropriate blade shape to generate power efficiently. Based on the inlet and outlet structure of the device, they know that the absolute fluid velocities, V1 and V2, are oriented as sketched below: At the inlet radial position, R1, of 2.4 m, the velocity, V1, is 18 m/s at an angle, 01, of 55° relative to the circumferential direction. At the outlet radial position, R2, of 1.3 m, the velocity, V2, is 8.4...

Q1. You are given a 12 V DC power supply. You are expected to develop a voltage divider to achieve a voltage of nominal 5V value using a pair of resistors from the E 12 range, with the restrition that you are not expected to draw a current of more than 1 mA from the 12 V DC supply i. Develop a simple circuit showing the possible values for each resistor pair, and the range of the DC output possible...
