Steam enters an adiabatic turbine with a pressure of 2 mpa and temperature of 250 c and leaves at 50 c. a) how much heat is transferred between the turbine and its environment? b) how much work is produced by this turbine if the process the steam experinces while passing through the turbine is internally reversible? c) what is the turbine outlet pressure if the isentropic efficiency of this turbine is 80%? d) how much work does the turbine produce if the turbine isentropic efficiency is 80%? explain the steps.

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.

Ariver flows from north to south at 8 km/h. a boat is to cross this river from west to east at a speed of 20 km/h (speed of the boat with respect to the earth/ground). at what angle (in degrees) must the boat be pointed upstream such that it will proceed directly across the river (hint: find the speed of the boat with respect to water/river)? a 288 b. 21.8 c. 326 d. 30.2
