Consider a steam power plant that operates on the idealreheatrankine cycle. the plant maintains the boiler at 7000 kpa, the reheat section at 800 kpa, and the condenser at 10 kpa. the mixture quality at the exit of both turbines is 93 percent. determine the temperature at the inlet of each tubine and the cycle’s thermal efficiency.

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?
