For some transformation having kinetics that obey the avrami equation (equation 11.17), the parameter n is known to have a value of 1.8. if, after 145 s, the reaction is 50% complete, how long (total time) will it take the transformation to go to 99% completion? y = - exp(-kt^n)

An air-conditioning system consists of a heating section and an evaporative cooler. air enters the heating section at 10°c and 70 percent relative humidity at a rate of 30m^3/min, and it leaves the evaporative cooler at 20°c and 60 percent relatively humidity. if the air conditioning system operates at a total pressure of 98 kpa, determine (a) the temperature and relative humidity of the air when it leaves the heating section, (b) the rate of heat transfer in the heating section, and (c) the rate of water added to air in the evaporative cooler
