Two kilograms of air within a piston-cylinder assembly executes a Carnot power cycle with maximum and minimum temperatures of 750K and 300K, respectively. The heat transfer to the air during the isothermal expansion is 60 kJ. At the end of the isothermalexpansion, the pressure is 600 kPa and the volume is 0.4 m3. Assuming the ideal gas model for air, determine the thermal efficiency.
Steam at 10bar and 0.95 dry flows at 130 m/sec in a pipe. It is throttled to 8 bar and the flow rate is 12 kg/sec. Assuming velocity in the pipe on the down stream side of the valve is 160 m/sec. Find the final condition of steam and the pipe diam..
If the maximum temperature in the cycle is not to exceed 2200 K, determine the thermal efficiency and the mean effective pressure.
Given an aerodynamic body, you have learned in Aerodynamics and Flight Mechanics how to apply the numerical Source Panel Method to this body to determine the velocity and pressure profiles along the surface of the body.
