The combustion gases (modeled as air) enter a turbine at 6atm, 1000K and exits at 1atm, 500K. Determine the isentropic efficiency if heat is transferred away from the surface at a rate of 10 kJ/kg at an average surface temperature of 350K.
Air (an ideal gas) contained in a rigid, insulated tank fitted with a paddle wheel, initially at 27 degrees celcius, 2 bar, and a volume of 2 m^3, is stirred until its temperature is 227 degrees celcius.
A Brayton cycle is the same as the Rankine cycle, but it takes place in the ideal gas region of states. A large stationary Brayton cycle gas-turbine power plant delivers a power output of 100 MW to an electric generator.
Your group manager tells you that she has heard that a sphere of AISI 1020 (HR) steel will produce plastic flow in the region of contact due to its own weight if placed on a flat plate of the same material.
An axial flow compressor stage has blade root,mean and tip velocities of 150,200 and 250 m/s. The stage is to be designed for a stagnation temperature rise of 20K and axial velocity of 150 m/s, both constant from root to tip.
