The speed of wind is U = 22.5 m/s. The pressure sensor shows the pressure the static pressure of the middle point line of the experiment surface as 6mmH20 under atmospheric pressure. absokute pressure is 99.1 KPa and temperature is 23 celsius. calculate the dynamic and static pressure of the middle point line of the experiment surface. calculate the static pressure of the tunnel walls and compare to the previous section static pressure. Why are they different?

1.) In Chapter 4 we will learn how a low-speed wind tunnel generates airflow to study aerodynamic shapes. Consider a tunnel that uses a U-tube mercury manometer attached between the bell inlet (station 1) and the test section (station 2) to measure the static pressure differential (por setting the airspeed of the flow. The pressure differential 1527 N/m2 for a test section airspeed of 50 m/s. What is the height of the unbalanced column of mercury?

For this problem, consider a site which is experiencing a wind speed of 9.5 m/s. You are to calculate how much power there is in the wind in Watts at this moment as it flows through the rotor of a wind turbine. Please assume that the air temperature is 14 degrees C at hub height conditions and the pressure can be considered to be 99.78 kPA for a rotor diameter of 32 m. (answer to 0 decimal places)
