Mucuna solannie is a Papilionaceace used in culinary. Its rheology using API specifications was evaluated. Compared with Carbogel, plastic viscosity of 17 against 16cP at 8ppb, yield point of 27 against 26 lb/100ft2 at 2ppb, 10 minutes gel strength of 17 against 15 lb/100ft2 at 6ppb, annular flow index of 0.46 against 0.42 at 8ppb, annular consistency index of 44.6 against 30.6 eq-centipoise at 2ppb, pressure drops of 10.43psi against 8.60psi at 2ppb, and cutting concentration of 1.272 vol. % against 1.215 vol. % at 8ppb were obtained. The results showed it has nano- particles

Mathematical model for leak location in natural gas pipeline has been developed in this paper. The model employs an isothermal steady state approach. Leak occurrence in the pipeline divides the pipeline into two sections-the upstream and downstream sections respectively. Analyses of leak incidences were carried out in the two pipeline sections giving rise to two equations being developed to address the leak localization. The first leak equation was developed by considering the upstream section of the pipeline while the second leak equation was developed by considering the downstream section of the pipeline. The two equations were analytically developed by slight modification of the Weymouth’s equation for gas flow in horizontal pipeline. Matlab software was used in the model simulation. Seven field data were used in the model simulation. The results from the Matlab simulation of the mathematical models developed gave the leak locations for each of the field cases. Comparison of the simulated results with actual results of leak locations determined experimentally revealed high level of accuracy with an average error of only 0.377% which is below the minimum acceptable limit. Furthermore analyses of results show that the two leak equations yield same results when used in the Matlab simulator. The model is highly suitable for accurate detection of leak in natural gas pipeline especially where economics and reliability is of essence.
