To Determine Moisture Content of Soil By Oven Drying Method

The water-content determination is a routine laboratory procedure. ASTM has designeated it with a Standard, ASTM D-2216-90 which can be found in “ASTM Standards vol. 4.08”, and also AASHTO T-265, found under “AASHTO Materials: Part II: Tests”. This is a laboratory procedure to determine the amount of water Ww present in a quantity of soil in terms of its

Pseudo Dynamic (PsD) Tests - Non Linear Structural Dynamics Techniques

PDT is a substructure technique which includes applying slowly varying forces to a structural model. The motions and deformations observed in the test specimens are used to infer the inertial forces that the model would have been exposed to

Laboratory Investigation of Hooke’s Law

Prepare the test specimen that is steel bar and find its diameter at tree different places and find its man value. Mark two points 8" a part of 2 ft long steel bar. Insert the bar in jaws for gripping the steel bar and select suitable bar on UTM. Place the steel bar and fix it.

Determination of Deflection in Over Hanging Beams

Take the beam model and place it on the table. it should be kept horizontally and firmly. Determine the length of the beam and also dimension of cross section.

Determination of Bending Moment in Beam

Take a beam model and place it on a table in such away that it should be horizontal and firm. Record the length and cross section. Set the deflection gauge at a point where the deflection is to be measured.

Experimental study of Laminar, Transitional and Turbulent Flow

The type of flow in which the particles move in a straight line in the form of a thin parallel sheets is known as the Laminar flow. Laminar flow denotes a steady condition where all stream lines follow parallel paths. Under this condition, the dye

Hydraulic Jump Experiment

Hydraulic jumps are very efficient in dissipating the energy of the flow to make it more controllable & less erosive. In engineering practice, the hydraulic jump frequently appears downstream from overflow structures (spillways), or under flow structures (sluice gates), where velocities are height. A hydraulic jump is formed when liquid at high velocity discharges into

Sieve Analysis of Coarse Grained Soil

Arrange different types of sieves in order of there decreasing size of opening. Find the total weight of the given soil sample and pour it in the top sieve.

To Perform Marshall Stability Test (ASTM D6927)

Marshal test is extensively used in routine test programs for the paving jobs. The stability of the mix is defined as a maximum load carried by a compacted specimen at a standard test temperature of 600 °C. The flow is measured as the deformation in units of 0.25 mm between no load and maximum load carried by the specimen during stability test (flow value may also be

Experiment - Various Parts of Hydraulic Bench

Hydraulic bench is a very useful apparatus in hydraulics and fluid mechanics. It is involved in majority of experiments to be conducted e.g. To find the value of the co-efficient of velocity ‘Cv’, coefficient of discharge ‘Cd’, to study the characteristics of flow over notches, to find metacentric height, to find head losses through pipes, to verify Bernoulli’s theorem

To Determine The Metacentric Height Of a Ship Model

The intersection of the lines passing through the original center of buoyancy and center of gravity of the body and the vertical line through the new center of buoyancy.

Calibration Of Rectangular Notch

A Notch is regarded as an orifice with water level below its upper edge. Notch is made of a metallic plate and its use is to measure the discharge of liquids. These are used for measuring the flow of water from a vessel or tank with no pressure flow. Since the top edge of the notch above the liquid level serves no purpose therefore a notch may have only bottom edge

To Measure COD of WasteWater using Open Reflux Method

KMn04 was used as oxidizing agent for many time pb with KMno4 was that different value of COD obtained due to strength change of KMno4. BOD value obtained greater than COD with KMno4 means KMno4 was not oxidizing all the substances.

California Bearing Ratio Test Procedure and Test Report

It is the ratio of force per unit area required to penetrate a soil mass with standard circular piston at the rate of 1.25 mm/min. to that required for the corresponding penetration of a standard material. The California Bearing Ratio Test (CBR Test) is a penetration test developed by

To Determine Yield & Tensile Strength of a Steel Bar

Loading Unit, control unit. In addition to these units, there are certain accessories like bending table, jaws for gripping recorders etc. Loading unit consists of two crossheads i.e upper cross head and lower cross head and a table
