It is insulated against heat, except for a cylinder base B with a volume of 100 liters. This cylinder It is divided into two compartments by a heat-proof and frictionless piston. 100 kPa pressure in chamber A and air at 20 oC temperature, and neon gas at 30 oC in compartment B. Initially the volumes of both compartments are equal. Compartment A at 800 kPa and 20 oC inside it is connected to a pipe with air flow. The valve opens and when the pressure in chamber A reaches 800 kPa is closed. In compartment B, neon gas is inverted and the temperature changes in a steady state. ww A) NEON'S FİNAL VOLUME AND COMPRESSİON WORK B) THE TEMPERATURE AND MASS OF THE AİR İN THE FİNAL CHAMBER A ww ww c) CALCULATE THE TOTAL ENTROPY CHANGE OF THE ENTİRE SYSTEM.

Air (MW=29 g/mol) at 115.00 kPa and 285.00 is compressed steadily to 600.0 kPa. The mass flow rate of the air is 2.00 kg/s and a heat loss of 32.1 kW occurs during the process. You may assume that changes in kinetic and potential energy are negligible, the temperature of the surroundings is 25 ∘C, and that the CP of air is 3.5 R. Given the compressor operates with a second law (reversible) efficiency of 0.60,calculate the following. What is the actual work interaction term in kW? What is the actual exit temperature of the air in Celcius?
An air compressor takes in air at a pressure of 100 kPa and a temperature of 300 K. The compressor is cooled at a rate of 15 k/kg and the mass flow rate is 50 kg/minute.
