A solution containing 20%(w/w) substance A is cooled prior to process B. The solution leaves an evaporator at a rate of 2000 kg h-1and must be cooled from 90°C to 6°C. Cooling is achieved by heat exchange with 2700 kg h-1water initially at 2°C. If the final temperature of the cooling water is50°C, what is th rate of heat loss from the solution A to the surroundings? Assume the heat capacity of substance A is 0.35 cal g-1C-.
