MECHANICS OF CONFINEMENT ------------------------------------------------------------------------------ 1. Preliminary Remarks Confinement of columns by means of FRP jackets is done by retraining the dilation of concrete by wrapping the fibers in the hoop direction of concrete columns. Confinement of columns by FRP wraps is termed as a passive strengthening technique since the fibers do not play any role in the elastic response of the axially loaded column. The tendency of concrete to

Katoda found the equation 0 − d 32 = 2330 ⋅ ρ 0‚121 ⋅ VB ‚131 ⋅ Δp B0‚135 ‚ L (5-1) for calculating the Sauter-Mean-Diameter for diesel injection nozzles. Thereby ρa is the air density‚ Vf the fuel volumetric flow and Δpf the pressure difference at the nozzle. The fuel volumetric flow can be replaced by the equation VB = u ⋅ A = 2 ⋅ Δp B π 2 ⋅ ⋅D ρB 4 (5-2) Thereby ρf is the fuel density and D the nozzle outlet diameter. The following equation achieved d 32 = 2362 ⋅ ρ

Gravimetric Analysis CHEM 200-03 Fall Semester 2012 September 19‚ 2012 Jeff Marasigan Abstract Gravimetric analysis is based on the quantitative isolation of the desired constituent the analyte of interest from the sample in highly pure form or in some combined form and weighing the isolated constituent. The desired constituent is usually isolated or separated by precipitation. From the weights of sample and precipitate‚ the percentage of the constituent in the original sample can

Modified Winkler method for dissolved oxygen determination Abstract In this study the group has determined the presence of oxygen in sample through a modified winkler method. The amount of oxygen is determined through a series of reaction. A body of water can sustain life if dissolved oxygen is sufficed. Depletions in dissolved oxygen can cause major shifts in the kinds of aquatic organisms found in water bodies. Introduction The amount of dissolved oxygen present in water or wastewater
