A perpetual-motion machine is designed by including the electrical generator to the steam power plant and redirecting part of the electricity generated by the generator to support the boiler. What type is this perpetual-motion machine

Define how a perpetual-motion machine that violates the second law of thermodynamics (PMM2).

For the NH3/H2O cycle the following relationship give the solution flow rate per unit refrigeration rate: WFS_A * X - WFS_G(X-1) = 1  where WFS_A = mass fraction of NH3 in solution form the absorber WFS_G = mass fraction of NH3 in solution from the generator X-1 =mass of solution from the generator per unit mass of refrigerant flow For large systems, a reasonable pressure drop between the evaporator and absorber is 1.5 psi Consider a large NH3/H2O plant operating per the schematic below:  Known/given: i. Refrigeration load = 500 tons ii. Evaporator temperature (state point 10) = 41.1 F iii. Evaporator pressure (state point 10) = 75 psia iv. Absorber pressure (state point 11) = 73.5 psia (per rule of thumb above regarding pressure drop between the evaporator and absorber) v. Strong aqua solution temperature (state point 3) = 105 F vi. Condenser temperature (state point 8) = 100 F vii. Condenser and tower pressure (state point 7) = 211.9 psia viii. Concentration split, WFS_G - WFS_A =6%…
