For some metal alloy it is known that the kinetics of recrystallization obey the avrami equation, and that the value of k in the exponential is 2.60 x 10-6, for time in seconds. if, at some temperature, the rate of recrystallization is 0.0013 s-1, what total time (in s) is required for the recrystallization reaction to go to 90% completion?

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.
