A steam entering a turbine with specific enthalpy h1=3524. kj/kg , and leaving with specific enthalpy h2=1256.2 kj/kg ,what is the output work of the turbine (kj/kg)?

Amass of 1.5 kg of air at 120 kpa and 24°c is contained in a gas-tight, frictionless piston-cylinder device. the air is now compressed to a final pressure of 720 kpa. during the process, heat is transferred from the air such that the temperature inside the cylinder remains constant. calculate the boundary work input during this process.

On a average work day more than work place firs are reorted

Steel is coated with a thin layer of ceramic to protect against corrosion. what do you expect to happen to the coating when the temperature of the steel is increased significantly? explain.
