An adiabatic air compressor is to be powered by a direct-coupled adiabatic steam turbine that is also driving a generator. Steam enters the turbine at 12.5 MPa and 500oC at a rate of 20 kg/s and exits at 10 kPa and a quality of 0.9. Air enters the compressor at 98 kPa and 295 K at a rate of 5 kg/s and exits at 1 MPa and 620 K. Using air and steam table, explain the net power delivered to the producer by the turbine and the rate of entropy change within the turbine and the compressor during this process. [The gas constant of air is R=0.287 kJ/(kg.K)].
A tank having 100 kg of a 60% brine (60% salt) is ?lled with a 10% salt solution at the rate of 10 kg/min and 78°F.Solution is detached from the tank at the rate of 15 kg/min. Fin

Q. What is the basic structure of Alkynes? Ans. Alcohols have the general chemical formula of ROH. The R stands for the rest of the molecule and is usually an alkyl group
Q. What is Entropy? Ans. The strangest thing about entropy is that it is denoted by the letter S. Entropy is the measure of the disorder in a system. A system with low en
