Milk at 40 ° C with a specific heat of 3.85 kj / kg K will be pasteurized at 75 ° C by using saturated steam at 120 ° C in a plate heat exchanger. The heat exchanger operates in parallel flow. What is the milk rate? The data required for steam is given in the table below.
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.
