Unsteady State Process Computations On Spreadsheets
(
Qatar University
, 1993 , Article)
Spreadsheets are becoming increasingly popular, as a useful tool, for making process engineering calculations. This paper shows the use of spreadsheets for computations of an unsteady state process described by ordinary ...
Effect Of Field Environmental Exposure Conditions On The Properties Of Hardened Concrete
(
Qatar University
, 1993 , Article)
The effects of harsh field environmental exposure conditions on compressive, tensile and flexural strengths and durability aspects of concrete such as chloride penetration, sulphate attack and carbonation were investigated ...
Amorphous Phase Properties Of Oriented Polyethylene Solids
(
Qatar University
, 1993 , Article)
Solid-state deformation of polyethylene results in a preferential orientation of both crystalline and amorphous regions. Usually, one major problem in the prediction of the mechanical and thermal expansion properties of ...
Effect Of Aspect Ratio On Torsional Capacity Of High-Strength Plain Concrete Deep Beams
(
Qatar University
, 1993 , Article)
Twenty high-strength plain concrete deep beams were tested under torsion. The variables were concrete strength and depth/width (aspect) ratio. Concrete strengths of 51.01, 58.53, 76.60 and 83.66 MPa and depth/width (aspect) ...
The Onset Of Resonance In Two-Immiscible Fluids Inside A Spinning And Coning Cylinder
(
Qatar University
, 1993 , Article)
Resonance of the motion of two fluids inside a cylinder that spins about its axis and rotates (cones) about an axis that passes through its center of mass is known to occur for low-viscosity fluids (high Reynolds number ...
Cone Penetration Testing For Field Density Prediction
(
Qatar University
, 1993 , Article)
This paper summarizes an experimental program for developing a pilot procedure to check and predict field densities of compacted soils using static cone penetration tests. Three sandy soils were tested. The testing program ...
A Case Study Of Traffic Characteristics And Proposed Improvement Schemes For An Arterial Road
(
Qatar University
, 1993 , Article)
This case study represents a typical example of surveying and assessing traffic characteristics along a local ring road in Doha City. Expected impacts of possible short-term (5-year) traffic management schemes for two main ...
Electrical Conductivity Of Aluminum Reinforced Graphite Electrodes
(
Qatar University
, 1993 , Article)
Composite, disc-like aluminum reinforced graphite electrodes were prepared, and an integrated parametric analysis has been performed to investigate the effect of some processing parameters on the electrical conductivity ...
Correlation Of Vapor-Liquid Equilibrium Data For Binary Mixtures Containing One Polar Component By The Parameters From Group Contributions Equation Of State
(
Qatar University
, 1993 , Article)
Use of a quadratic mixing rule in the Parameters from Group Contributions Equation of State increases the range of compounds for which vapor-liquid equilibrium behavior can be satisfactorily correlated. This is demonstrated ...
Unsteady-State Interphase Diffusion
(
Qatar University
, 1993 , Article)
This study is concerned with the problem of unsteady interphase diffusion for multicomponent dilute solutions. An integral technique, based on an approximate boundary-layer approach is used. Results are in good agreement ...
