High - pressure air at 500 kPa and 30°C is to be used to drive a small turbine for a powering high speed drill. The drill requires a power input of 746W, and the air from the turbine may be assumed to discharge at 180 kPa. The turbine is well insulated and the process may assumed steady. As a dsesign engineer you are required to do the following.
A) calculate the mass flow rate of air required to run the drill ( assume constant specfic heats )
B) If the inlet air line is 1cm in diameter, calculate the entering air velocity.
