Steam at 160 bar and 550 degree centigrade is supplied to a steam turbine. the expansion of steam is adiabatic with increase in entropy of 0.1 kj/kg k. find the inlet and exhaust conditions of steam. if the exhausted pressure is 0.2 bar, calculate specific work of expansion. and use steam table sketch in t-s diagram.

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

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines
