Consider 6.9 kg of austenite containing 0.40 wt% C, cooled to below 727˚C (1341˚F). (a) What is the proeutectoid phase? (b) How many kilograms each of total ferrite and cementite form? (c) How many kilograms each of pearlite and the proeutectoid phase form? See Animated Figure 9.24

100 kg/hr of aqueous mixture containing 74 %wt of sucrose is cooled from 60 ˚C to...

100 kg/hr of aqueous mixture containing 74 %wt of sucrose is cooled from 60 ˚C to 20 ˚C. Due to the decrease in temperature, some of the sugar precipitates out from the mixture as crystals and are subsequently removed via a separator unit. In the separation of the crystals, for every 1 kg of crystals removed, 0.05 kg of the aqueous mixture will be removed together with the crystals. Calculate the mass flow rate of the remaining saturated aqueous solution (in kg/hr)....

If a steel plate containing 0.68 wt% C is carburized at 1000°C in an atmosphere containing 2.19 wt% C, how long will it take for the carbon concentration to be 0.861 wt% at a depth of 1.67mm from the surface of the plate? The equation for the diffusivity of carbon is given by D(T)=1.62x10^{-5}*Exp(-137000/RT)

Bananas are to be cooled from 28°C to 12°C at a rate of 1140 kg/h by a refrigerator that operates on a vapor-compression refrigeration cycle. The power input to the refrigerator is 9.8 kW. Determine (a) the rate of heat absorbed from the bananas, in kJ/h, and the COP, (b) the minimum power input to the refrigerator, and (c) the second-law efficiency and the exergy destruction for the cycle. The specific heat of bananas above freezing is 3.35 kJ/kg·°C.
