Hence we can conclude that in order to pump 2500 m 3 /hr at the bottom level in the reservoir, the pump will need to overcome a system pressure of 10.39 m. At the top level, the pump will only need to overcome a system pressure of 6.79 m. If a

Check for convergence because all three correlations must converge to the same R2 goodness-of-fit.. 3. Test for predictability. Success is defined when the predictive

Learn MoreThe model accounts for the pass time, bleeding, and the environmental evaporation rate to estimate the surface moisture and predict the lack of interlayer adhesion. In this study, the model accurately (RMSE = 2.5%) predicted an interlayer adhesion reduction from 30% to 50%. The interlayer adhesion results of other studies could also be predicted.

Learn More1. Introduction. In the past 10 years, 3D concrete printing has received increasing attention in academia and the construction industry. The technology promises more design freedom, less waste material, faster construction time, reduced cost and, most importantly, increased workplace safety [1,2].High-performance concrete mixes (HPCM) with water to binder ratios between 0.21 and 0.41 are

Learn MoreThe book aims to provide an unifying view of a variety (a 'zoo') of mathematical models with some kind of singular nonlinearity, in the sense that it becomes infinite when the state variable approaches a certain point. Up to 11 different concrete models are analyzed in separate chapters. Each chapter starts with a discussion of the basic model
