A225 mwe conventional gas-turbine power plant has a thermal efficiency of 25%. the natural gas fuel, which is 99% methane (ch4) and 196 hydrogen sulfide (h2s) by volume, has a heating value of 36,500 kj/m^2. at full power conditions, compute (a) the fue consumption [in m3/sec], and (b) the s02 production [in m3/sec) in the plant.

Line joining liquid phase with liquid and solid phase mixture is known as: a) liquidus b) solidus c) tie line d) none of the mentioned

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented
