TL;DR: In this article, thermal conductivity, dynamic viscosity and Nusselt number of turbulent forced convection of Magnesium Oxide-water nanofluid in a circular straight pipe is presented.
Abstract: In the present paper results of an experimental study on thermal conductivity, dynamic viscosity and Nusselt number of turbulent forced convection of Magnesium Oxide–water nanofluid in a circular straight pipe is presented. The considered pertinent parameters are Reynolds number, nanoparticles volume fraction and nanoparticles diameter. The pure water and nanofluid with the nanoparticle volume fraction of 0.005, 0.01, 0.015, 0.02 and the nanoparticles diameter of 60, 50, 40 and 20 nm are considered. The experimental values of the thermal conductivity and the dynamic viscosity shows that traditional formulas underestimates these thermophysical parameters. Also the experimental results indicates that the existence of the nanoparticles in the pure water with all considered values of the nanoparticles volume fraction and diameter motivates the rate of heat transfer to increase. The nanofluids with higher volume fraction and smaller nanoparticles diameter results in higher Nusselt number.

TL;DR: In this article, the mechanical properties of glass bead filled epoxy and polyester resins have been studied as a function of volume fraction of filler and the strength of the interfacial bond.
Abstract: The mechanical properties of glass bead (30 micron diameter glass spheres) filled epoxy and polyester resins have been studied as a function of volume fraction of filler and the strength of the interfacial bond. The bonding between glass and resin was varied by chemically surface treating the glass using a silicone mold release to prevent chemical bonding at one extreme and a silane coupling agent to maximize bonding at the other extreme. Theoretical predictions of the elastic modulus and tensile strength have been made utilizing a finite element method. Excellent agreement is obtained with the experimental results. Izod impact energies have been measured for these composites as a function of filler content and interface treatment.
