In this chapter, we will discuss the increase of heat transfer as well as the increase in pressure drop to determine whether nanofluid is feasible for use in practical applications. Addition of nanoparticles will change the thermal properties of the cooling fluid, by calculation with performance evaluation criterion (PEC). If PEC < 1, then the heat transfer performance is less than the pumping power, so the system is not feasible for use in increasing heat transfer. If PEC = 1, then the heat transfer performance is smaller equal to the pumping power so that the system does not have an impact on increasing heat transfer. If PEC > 1, then the heat transfer performance is higher than the energy used to drive the fluid or pumping power, and then it can be accepted as a solution to the problem of increasing heat transfer, so that the system is feasible for use in practical applications.
