The research aims to design and construct a device to measure the drag coefficient for the free falling and accelerating bodies in different fluid mediums. Four main factors are know to have an effect on free falling bodies. These factors are: shape, size density of the body and density of the medium through which the body travels. In this study, spherical and cylindrical shape bodies were investigated.

The aim of this work is to design, construct and evaluate the performance of a solar water heater system called a novel solar collector system [2] with an experimental and mathematical calculation, where the behavior of the collector is mathematically presented.

The present study has been carried out to investigate the problem of heat transfer by force convection as unsteady state conduction ((i.e. lumped-capacitance system)) from the out side surface of horizontal cylinder in cross flow of air was studied. Experimental works were involved for this purpose.
