If the entropy change of an adiabatic, closed system process is positive, the process is which of the following? Impossible, irreversible, externally reversible, internally reversible?
The entropy change between two specified states is the same whether the process is reversible or irreversible.
A turbine operating under steady flow conditions receives steam at the following state:p1 = 1.5 bar, v1 = 0.038 m3/ kg, C1 = 115 m/s and u1 = 915 kJ/kg and at the exit are p2 =5.5 bar, v2 = 0.18 m3/kg, C2 = 195 m/s and u2 = 715 kJ/kg. During the passage, the fluidrejects 850 kJ/hr heat. If the rate of steam flow is 1368 Kg/hr. Evaluate the powerdeveloped by the turbine in kW.
In a steady flow process, the working fluid flows at a rate of 240 kg/min. The fluid rejects 120 kJ/s passing through the system. The conditions of fluid at inlet and outlet are given as : C1 = 300 m/s, p1 = 6.2 bar,u1 = 2100 kJ/kg, v1 = 0.37 m3/kg and C2 = 150 m/s, p2 = 1.3 bar, u2 = 1500 kJ/kg, v2 = 1.2 m3/kg. The suffix 1 indicates the conditions at inlet and 2 indicates at outlet of the system. Neglecting the change in potential energy, determine the power capacity of the system in MW.
SANAE IV, a research station of The South African National Antarctic Programme (SANAP), is located on Vesleskarvet, Queen Maud Land. On a given day, 29674 J of heat leaks out of a building. The inside temperature is 22.8 °C, and the outside temperature is -20.2 °C. What is the increase in the entropy of the universe that this heat loss produces?
Steam enters a converging-diverging nozzle operating at steady state with P-40 bar, T-400°C, and a velocity of 10 m/s. The steam flows through the nozzle adiabatically and no significant change in elevation. At the exit, p2=1.5 MPa, and the velocity is 665 m/s. The mass flow rate is 2 kg/s.
