A meteorologist uses a pitot-static tube to measure the wind speed in a tornado. Based on the damage caused by the storm, the tornado is rated as EF5 on the enhanced Fujita Scale. This means that the wind speed is estimated to be in the range of 261 to 381 mph. is it reasonable to use the incompressible pitot-tube equation (3.16) to determine the actual wind speed, or must compressible effects to taken into account? Explain
