1.An air turbine is used with a generator to generate electricity. Air at the turbine inlet is at 700 kPa and 25 degree C. The turbine discharges air in to the atmosphere at a temperature of 11 degree C.Inlet and outlet air velocities are 100 m/s and 2 m/s respectively. Determine the work per unit mass delivered to the turbine from the air.
2.What is differential equation for beams subjected to axial compression,esp.with initial imperfection to the fixed-hinged column?
