A 100 mm concrete wall is to be used to make a cold storage. The floor and ceiling is to use the same material. The room is supposed to have height of 5 m, length of 7 m and a width of 6 m. The ambient temperature is 36 degrees and the room has to be cooled at 3 degrees. The cold storage is to be used to cool 1600 kg of milk. Conduct the cooling load calculation for the room and determine the cooling capacity of the cooling equipment required for this room.

Fluid Materials

In general terms, anything that flows can be termed as a fluid. In other words, a fluid is any substance that cannot resist shear forces and deforms continuously under the application of external shear forces. Fluid materials differ completely from solid materials such as metals and alloys. For instance, if we consider two infinitesimally small cross-sectional areas of fluid materials and solid materials, and apply shear forces to these elements, both the elements will undergo deformation. Upon releasing the shear force, the element of the solid materials will regain its original orientation, but the element of the fluid materials will keep on deforming continuously under the action of the shear force.
