A well-insulated piston-cylinder assembly is connected by a valve to an air supply line at 8 bar (1 bar=100 kPa), as shown in figure below. Initially (state 1), the air inside the cylinder is at 1 bar, 300 K, and the piston is located 0.5 m above the bottom of the cylinder. The atmospheric pressure is 1 bar, and the diameter of the piston face is 0.3 m. The valve is opened and air is admitted slowly until the volume of air inside the cylinder has tripled (state 2). The weight of the piston and the friction between the piston and the cylinder wall can be ignored. Assuming the air behaves as an ideal gas and heat lost during the process is 1.10 kJ, calculate the temperature (K) of the air in the supply line and the mass (kg) of the air added in the cylinder considering that the final temperature is 219°C
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
