Thermodynamics question: Isentropic turbine vs. un-insulated turbine: True or False 1.)The un-insulated turbine will produce more work 2.)The isentropic turbine will contribute more entropy to the environment 3.)The efficiency of the isentropic turbine will always be greater than that of the un-insulated turbine 4.)The un-insulated turbine will produce no work
1. The heat produced in a boiler is transferred from the combustion products to the water. While the temperature of the combustion products decreases from 1100 °C to 550 °C, the pressure remains constant at 0.1 MPa. The average specific heat at constant pressure of the combustion products is 1.09 kJ/kg.K. The water enters the system at 0.8 MPa and 150 °C, and leaves at 0.8 MPa and 250 °C. Determine the second law efficiency and the irreversibility for each kilogram of water vaporized for this process. Note: This is a thermodynamics course question. Please provide a solution that is clear and quick.

The Stirling cycle (the cycle undergone by the gas inside the Stirling engine shown in the video in class)consists of the following processes:• A → B: Isochoric heating from a temperature TA to a temperature TB > TA.• B → C: Isothermal expansion from volume VA to a volume VC > VA.• C → D: Isochoric cooling from TC = TB to TD = TA.• D → A: Isothermal compression back to volume VA.Assume the gas can be treated as a monoatomic ideal gas and that there are n moles of gas in the engine.

After combustion, the gases reach a temperature of 2000°R before being discharged through the nozzle at 6 lbf/in.2 On the basis of an air-standard analysis, determine:(a) the pressure at the diffuser exit, in lbf/in.2(b) the velocity at the nozzle exit, in ft/s.Neglect kinetic energy except at the diffuser inlet and the nozzle exit.
