If 500 g of a 40 wt% ag–60 wt% cu alloy is slowly cooled from 1000°c to just below 780°c (see fig. p8.23): a. how many grams of liquid and proeutectic alpha are present at 850°c? b. how many grams of liquid and proeutectic alpha are present at 780°c + δt? c. how many grams of alpha are present in the eutectic structure at 780°c − δt? d. how many grams of beta are present in the eutectic structure at 780°c − δt?

What is the main objective of using reheat rankine cycle?

Liquid flows at steady state at a rate of 2 lb/'s through a pump, which operates to raise the elevation of the liquid 100 ft from control volume inlet to exit. the liquid specific enthalpy at the inlet is 40.09 btu/lb and at the exit is 40.94 btub. the pump requires 3 btu/s of power to operate. if kinetic energy effects are negligible and gravitational acceleration is 32.174 tt/s, the heat transfer rate associated with this steady state process is most closely 1)-2,02 btu/s from the liquid to the surroundings 2)-3.98 btu/s from the surroundings to the liquid. 3)-4.96 btu/s from the surroundings to the liquid. 4)-1.04 btu/s from the liquid to the surroundings.

What is the direction and how to operate the lathe?
