An experiment was conducted to test the effects of a high-protein diet on the ability of chickens to lay eggs that have a high-protein content. ten chickens were obtained from three chicken-breeding farms (all were hens), and their diet consisted of a mixture of fish, cheese, and soybeans. eggs produced from this group of chickens were found to have a slightly higher protein content than eggs purchased at a local grocery store. from this, the investigator concluded that the diet fed to the chickens was responsible for the protein increase in the eggs. how would you analyze these results, using critical thinking?

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.
