WebA steady-flow system receives 1 kg/s of a substance with U1 = 1000 kJ/kg, P1= 500 kPa, s.v.= 1.2 m3/kg, and v1= 50 m/s. There is a heat loss of 100 kJ /kg, and the fluid exits at v2=150 m/s, s.v.=0.7 m3/kg , P2= 100kPa, and H2 =1150kJ/kg. Determine the change in kinetic energy in kJ/kg. Round off your answer to the nearest whole number. WebWe study a quantity T defined as the energy U, stored in non-equilibrium steady states (NESS) over its value in equilibrium U 0 , Δ U = U − U 0 divided by the heat flow J U going out of the system. A recent study suggests that T is minimized in steady states (Phys.Rev.E.99, 042118 (2024)). We evaluate this hypothesis using an ideal gas system …
