An aircraft is in its take off roll at sea level with ambient temperature of 18°C. What is the approximate speed of the aircraft if the temperature measured by a probe at the exist of the engine diffuser is $$36^\circ$$ C? (Assuming air Stagnation at diffuser outlet and $$C_{p}$$ of air as 1.0 $$\frac{kJ}{Kg.K}$$)

A

12 $$\frac{m}{s}$$

B

3 $$\frac{m}{s}$$

C

6 $$\frac{m}{s}$$

D

18 $$\frac{m}{s}$$
