stream of vapor-free gas is passed. A water bath is provided for maintaining a steady temperature so that there is no eddy current in the vertical tube and mass transfer takes place from the surface by molecular diffusion alone. The rate of evaporation can be followed by the rate of fall of the liquid surface. A traveling microscope is provided for determining‚ the liquid fall. With the knowledge of the concentration gradient‚ the diffusivity of the vapor of the volatile liquid can then be calculated

probes successfully landed on the surface of the Venus. However‚ the essential equipment on probes was damaged‚ leading to that it failed to get insight into the surface of the Venus. While‚ on 17th August 1970‚ with the experiences from the previous two attempts‚ "Venus 7" lander completed their missions on the surface of the Venus successfully. The lander gauged the atmospheric pressure on the surface of the Venus‚ which illustrated that the pressure on the Venus’ surface was at least 90 times stronger

Effects of Pesticide Case Study INTRODUCTION The Bago City is the rice granary of Negros Occidental. The farmers of Bago City are struggling because of the pest. They have decreased their production of rice because of the pest. Our goal of engaging this case study is to analyze and see the effect of the pesticide to the crops. We are to seek good and bad effects of these pesticides. We’re going to focus only on finding the effects of these pesticides so we can come up with a good report. By observing

Modern-Surface Mining When coal seams are near the surface‚ it may be economical to extract the coal using open cut (also referred to as open cast‚ open pit‚ or strip) mining methods. Open cast coal mining recovers a greater proportion of the coal deposit than underground methods‚ as more of the coal seams in the strata may be exploited. Large Open Cast mines can cover an area of many square kilometers and use very large pieces of equipment. This equipment can include the following: Draglines which

perpendicular to or normal to the section is called the normal stress. Normal stress may be tensile or compressive. Tensile stress: stresses that cause pulling on the surface of the section‚ (particles of the materials tend to pull apart causing extension in the direction of force) Compressive stress: stresses that cause pushing on the surface of the section‚ (particles of the materials tend to push together causing shortening in the direction of force) Strain • If a bar is subjected to a direct

There are two types of seismic waves‚ Body waves and surface waves. Body waves travel through the interior of the earth. Surface waves travel along the earth’s surface and through water. Seismic wave fields are measured by a seismograph‚ geophone‚ hydrophone or accelerometer. These are used to measure earthquakes. When measuring these earthquakes these

Low Stony Hill is also composed a variety of species of forbs. The soils at this site include Eckrant cobbly silty clay (EcB) soils ranging from shallow to very shallow; however‚ the soil is well drained with moderately slow permeability and rapid surface runoff with 1-3 percent slopes. Methods Soil characteristics‚ which affect infiltration rates and are crucial to understanding infiltration‚ include bulk density‚ vegetation‚ and microtopography. To assess and calculate these characteristics‚ 32 microplots

of the sphericity F s‚ which is independent of particle size. The sphericity of a particle is the ratio of the surface-volume ratio of a sphere with equal volume as the particle and the surface-volume ratio of the particle. For a spherical particle of diameter D p‚ F s =1; for a non-spherical particle‚ the sphericity is defined as Dp: equivalent diameter of particle Sp: surface area of one particle vp: volume of one particle The equivalent diameter is sometimes defined as the diameter of
