Air is contained in a vertical piston-cylinder assembly by a piston of mass 50 kg and having a face area of 0.01 m2. The mass of the air is 5 g, and initially the air occupies a volume of 5 L. The atmosphere exerts a pressure of 100 kPa on the top of the piston. The volume of the air slowly decreases to 0.002 m3 in a quasi-equilibrium process as the specific internal energy of the air decreases by 260 kJ/kg. Neglecting friction between the piston and the cylinder wall, determine the heat transfer to the air in k.
The heat transfer convection coefficient between the wall and the fluid is 500 W/m2.K. Find the maximum temperature in wall.
Crank AB of the linkage shown rotates clockwise at 300 rpm. Using graphical method, determine the velocity of point B, C, D, and E.
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.
