1.	Which of the following is the general equation that relates flow temperature to true airspeed?(a) CpT+\(\frac{V^2}{2}\)=constant(b) CpT-\(\frac{V^2}{2}\)=constant(c) CvT+\(\frac{V^2}{2}\)=constant(d) CvT-\(\frac{V^2}{2}\)=constantThis question was addressed to me in an international level competition.The above asked question is from Measurement of Airflow Characteristics in division Atmosphere and Air Data Measurement of Aircraft Performance
Answer» Correct choice is (a) CPT+\(\frac{V^2}{2}\)=constant The explanation: CpT+\(\frac{V^2}{2}\)=constant is the general equation that RELATES flow TEMPERATURE to true airspeed, where Cp=specific HEAT at constant PRESSURE, T=temperature, V=true airspeed.
