Water rises to a height of 10 cm. in a certain capillary tube. If in the same tube, level of Hg is depressed by 3.42 cm., compare the surface tension of water and mercury. Sp. Gr. Of Hg is 13.6 the angle of contact for water is zero and that for Hg is135∘. ...
NCERT solutions for CBSE and other state boards is a key requirement for students. Doubtnut helps with homework, doubts and solutions to all the questions. It has helped students get under AIR 100 in NEET & IIT JEE. Get PDF and video solutions of IIT-JEE Mains & Advanced previous year pap...
3.10 Ma. Results showed that there was no obvious change overall in chemical composition along the direction of groundwater runoff, but different hydrochemical processes occurred in shallow and deep groundwater in the vertical direction. Shallow groundwater (< 150 m) in the Xiong ’an New Area ...
The image below shows a glass pipe with water flowing inside it. Explain what you observe. Reynolds Number: The Reynolds number is the ratio between the density, viscosity, velocity, and typical dimension of a flow in a dimensionless expression. The Reynolds number is...
Certain aquatic insects rapidly traverse water by secreting surfactants that exploit the Marangoni effect, inspiring the development of many self-propulsion systems. In this research, to demonstrate a new way of delivering liquid fuel to a water surface
At 0 mA cm−2 the corners and edges of the cathode flow field are wetted by condensing water, visible as a dark shading along the edges. With increasing current density, the water consumption of the cathode reactions rises and the shading in the cathode channel gets gradually lighter ...
vertical motions (upward and downward motions) of the free surface result in the change of air pressure within the air chamber. At the top of the chamber, another narrow opening is installed to allow the passage of airflow. As the water level rises, the air entrapped within the chamber is...
S4), which suggests that they can mainly be attributed to denitrification in the top soil layers. Denitrification sharply increases when the soil moisture content rises above a certain threshold degree of saturation (Heinen, 2006). Due to the relatively high organic matter content, originating from...
Why does the blood of injured deep-sea divers look greenish-black in underwater photographs taken with natural lights? The longer the board and the shallower the water, the farther will a surfboard skim across the water. Explain. Explain how a submarine rises, falls, ...
The water-gas pressure difference at the evaporating gas-liquid interface decreases as humidity rises. In SDWE, the condensation behavior is such that the water-vapor pressure difference within the device does not remain 0 forever, but the persistently low water-vapor pressure difference forces the...
