Study of Physical and Chemical Properties of Heavy Waxy Crude Oil from Cambay Basin Using Rheometer and Cross-Polar Microscope
Abstract: Production of heavy crude is quite difficult as the pressure drops from reservoir to production facility are quite large. This often leads to the precipitation and deposition of common organic solids (paraffin). These solids may deposit on surfaces, collect in low-energy regions or increase the effective viscosity of the flowing fluid. The net effect is an increase in pressure drop for a given rate through reduction in flowing area or …

Optimization of Roof angle for Sloping Roof Buildings under Extreme Wind Conditions
Abstract: A downburst that occurs during a thunderstorm is a strong downward current of wind which comes down with high speed from the cloud level and hits the ground. After hitting the ground it spreads radially outward in all directions. These are generally destructive in nature. There are evidences of downburst causing extensive damages to buildings, electrical installations etc. In India thunderstorms often occur during pre-monsoon and post-monsoon seasons particularly in …
