A heat exchanger is used to cool 100 kgh1 of tomato paste with a solid content of 40% from 90C to 20C. The temperature of the cooling water (used in heat exchanger) should not increase more than 10C. The water and tomato paste are not mixed in the heat exchanger. Draw a block diagram for the mass and energy flows in this problem. Determine the amount of water that must be supplied to this heat exchanger. The specific heat follows Seibel's equation:

Cp (Jkg1K1) = 837.36 + (33.49 x % moisture)
