Here the common problem on Work Done by Ideal Gas Topic. Please try to solve the problem!
No. 1
A rigid tank contains air at 500 kPa and 150°C. As a result of heat transfer to the surroundings, the temperature and pressure inside the tank drop to 65°C and 400 kPa, respectively. Determine the boundary work done during this process.
No. 2
A frictionless piston–cylinder device contains 20 atm of steam at 320oF. Heat is now transferred to the steam until the temperature reaches 400oF. If the piston is not attached to a shaft and its mass is constant, determine the work done by the steam during this process.
No. 3
A piston–cylinder device initially contains 0.4 m3 of air at 100 kPa and 80°C. The air is now compressed to 0.1 m3 in such a way that the temperature inside the cylinder remains constant. Determine the work done during this process.
No. 4
During actual expansion and compression processes of gases, pressure and volume are often related by PVn = C, where n and C are constants. It is called polytropic process. Determine the work done by the process!
No. 5.
Two frictionless piston–cylinder has same volume at 150 cc. One of them has 2 times larger radius the the other one. If you want to use the cylinder to make a high speed motorcycle, which one you prefer? Image the rate of cycle of those cylinder are equal.
