i need help with this please Design a hydrocooling unit that can cool fruits andvegetables from 30 to 5°C at a rate of 20,000 kg/h under thefollowing conditions:The unit will be of flood type, which will cool the productsas they are conveyed into the channel filled with water. Theproducts will be dropped into the channel filled with water atone end and be picked up at the other end. The channel can beas wide as 3 m and as high as 90 cm. The water is to be circulated and cooled by the evaporator section of a refrigerationsystem. The refrigerant temperature inside the coils is to be–2°C, and the water temperature is not to drop below 1°C andnot to exceed 6°C.Assuming reasonable values for the average product density,specific heat, and porosity (the fraction of air volume in abox), recommend reasonable values for (a) the water velocitythrough the channel and (b) the refrigeration capacity of therefrigeration system.
