In this research work an attempt was made to develop a response surface model to predict tensile strength of inert gas metal arc welded AISI 1040 medium carbon steel joints. The process parameters such as welding voltage, current, wire speed and gas flow rate were studied. The experiments were conducted based on a four-factor, three-level, face centred(More)
Water budget models are commonly accepted methods for estimating the groundwater recharge. Some of the inputs to these models such as soil-moisture deficit, actual evapotranspiration, direct runoff etc, are difficult to measure. The space dynamic nature of these parameters makes their quantification even more difficult. The error in estimation increases(More)
