It is very essential to develop a forced convection system to carry out the analytical and experimental investigation of the heat transfer coefficient with the use of the elliptical and circular pipe. Convection is nothing but the transfer of heat through a fluid which is in bulk fluid motion. Depending on the motion of the fluid, it is classified as natural and forced convection. Buoyancy effect is the natural cause which occurs due to fluid motion in natural convection. On the other hand, in forced convection, the motion of the fluid is caused by external means like a pump or fan. In this system three, 130 Volt heaters are wounded over 800 mm test section of Circular pipe having a 25mm diameter and Elliptical pipe having 22 mm minor and 28 mm major diameter. Variable dimmer stat is used to control input to heater and control valve to control mass flow rate, to determine the average coefficient of heat transfer in turbulent flows inside smooth and straight Circular and Elliptical pipes. The research consists of a regression analysis performed between the Reynolds number and the Prandtl number finally to calculate the heat transfer coefficient of Circular and Elliptical pipes by experimental investigation. After calculating all the results of both the pipes finally we got that efficiency of Elliptical pipe is more than circular pipe also heat transfer coefficient is maximum in the elliptical pipe than the circular pipe and it also led to increasing the heat transfer rates. The deviation of the heat transfer coefficient is maximum as compared to Elliptical pipe.

This paper aims at experimental analysis of composite box beam to estimate the material uncertainty. The deflection parameter has considered for analyzing the uncertainties present in material. The composite box beam is like a cantilever beam, where one end is fixed and at free end load is applied. In previous study free end deflection is calculated using Dial Gauges whose stylus will make point contact with proposed setup. But due to this contact it will create instrumental errors or manual error during experimentation. To avoid such situation the non contact device is developed called as Hall Effect Sensor which is the electronic device and it is works on electromagnetic field. If magnet is come in front of sensor it create magnetic field between them. The change in voltage or field is calibrated in terms of deflection of beam. In this paper, experimentation has carried out on four composite box beams which are manufactured by same process to find the material uncertainties and then the results are validated with COMSOL Multiphysics, software for same parameters.
