problem 2: What are the different modes of work and prepare brief notes on:

a) Shaft work.
b) Flow work.

problem 3: Air expands from 3 bar to 1 bar in a nozzle. The initial velocity is 90 m/s and temperature is 150oC. Estimate the final velocity. Cp = 1.005 kJ/kg K.

problem 4: prepare brief notes on:

a) Isobaric Process.

problem 5: Steam enters a turbine at a velocity of 12 m/s and specific enthalpy is 2960 kJ/kg. At the exit of the turbine, the steam velocity is 30 m/s and the specific enthalpy is 2400 kJ/kg. The heat lost throughout the flow via the turbine 20 kJ/kg and the steam flow rate is 85 kg/s. Find out the work output from the turbine.
