There are two buckets of water, both lying at a height of 10m above the ground: bucket a: at 90 deg. c, contains 1kg of water bucket b: at 50 deg. c, contains 2kg of water 00kj of energy is to be extracted from one of the buckets. the best quality of energy can be extracted from o bucket a o bucket b energy extracted from both the buckets will have the same quality

To design a steam turbine to produce 12,000 hp power. a engineer comsiders using a steady state stean low st 1160fr and engineer considers using a steady state steam flow at 1160°r and 450 psia to drive this steam turbine. the exhaust of the steam is cooled by the lake (vacuum). heat losing to the surroundings is measured at a rate of 555.55 btu/s. (a) sketch the system with the given conditions. (b) neglecting kinetic and potential energy changes from inlet to exit, determine the volumetric flow rate of the steam at the inlet, (ft'/hr). must clearly show unit conversions at crtical terms.
