An insulated gas turbine is attached to the exhaust stack of an oil-fired boiler in a power plant. The pressure and temperature at the inlet to the turbine are 0.500 MPa absolute, 1000.°C and the exit pressure is atmospheric. The exhaust gas analysis by volume is 12.0% CO2, 2.00% CO, 4.00% O2, and 82.0% N2.
What is the maximum possible power output from this turbine per kg of exhaust gas flowing through it? Assume that the exhaust gas is an ideal gas and ignore all kinetic and potential energy effects.
A particle falls to Earth starting from rest at a great height(many times Earth's radius). Neglect air resistance and show thatthe particle requires approximately 9/11 of the total time of fallto traverse the first half of the distance. [Note: You wi..
