The plant maintains the boiler at 17.5 mpa, the reheater at 2 mpa, and the condenser at 50 kpa. the temperature is 550°c at the entrance of the high-pressure turbine, and 300°c at the entrance of the low-pressure turbine. determine the thermal efficiency of this system. use steam tables the thermal efficiency of this system is%.

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
