Asteam power plant operates on as illustrated in the figure below (follow the numbers from the problem statement not the figure), however it only includes one feedwater heater. steam enters the turbine at 4,500 kpa and 500 c and exhausts at 20 kpa. steam for the feedwater is extracted from the turbine at 350 kpa, and in condensing raises the temperature of the feedwater to within 6 c of its condensation temperature at 350 kpa. if the turbine and pump efficiencies are both 0.78, what is the thermal efficiency of the cycle and what fraction of the steam entering the turbine is extracted for the feedwater heater? note.- i would suggest you use the figure to create your own with the information from the problem statement.

wind moving at higher speeds will transfer more energy to the water, resulting in stronger waves.

true tan speed = ang vel x radius

the small 0.38-kg slider is known to move from position a to position b along the vertical-plane slot. determine (a) the work done on the body by its weight and (b) the work done on the body by the spring. the distance r = 0.70 m, the spring modulus k = 154 n/m, and the unstretched length of the spring is 0.53 m

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
