oil level indicators

Oil and oil wastes enter rivers and other water bodies from different sources such as oil refineries, storage tanks, petro-chemical plants, industrial effluents, oil tanker spillage and automobile waste oil. Normal tanker operations and spillage fr..

The base radius of a right circular cylindrical oil container is 90 m. Oil is drawn from it at the rate of 729000 m 3 per minute. Find the rate at which the oil level falls in the container. => 9 0 π m/min or 7 2 9 0 π m/min or 8 1 0 π m/min or 1 &pi..

The senior surgeon of St. Ann's hospital claims that many patients who undergo heart surgery build up anxiety. Six patients were tested for anxiety before and after the surgery. The test results indicating the level of anxiety are tabulated. Find the test value and check whether..

If the emulsion can be diluted with water, this indicates that water is the dispersion medium and the emulsion is of oil-in-water type. If water forms a separate layer, the emulsion is water-in-oil typ..

Fractional Distillation of Oil The fractionating column is a tall steel tower attached to an electrically heated furnace. Throughout the length of the tower, there are trays with raised holes covered with loose fitting caps called the bubble caps. These caps allow the vapors to rise ..

Heat energy is present in every object above absolute zero. How do we know that heat is present in every object? Temperature of the body is an indication. (Absolute zero is the lowest temperature possible and is equal to -273 o C). Are heat and temperature one and the same? No. They are d..

Small drops of oil formed by a sprayer are allowed to fall in between a positively charged upper metal plate and a negatively charged lower metal plate. The space between the two plates is irradiated with X-rays. This displaces some electrons of the air molecules, which consequently get ..

Electronic Configurations of Atoms - The distribution of electrons in different orbitals is known as electronic configuration of the atom. The orbitals are indicated by a box (square or circular) and electrons are indicated by arrows. An empty square will mean an empty orbital, ..

Quantum Numbers - Orbitals of electrons in atoms differ in size shape and orientation. Definite energies and angular movements characterize atomic orbitals. The state of an electron in any atom is defined by certain permissible values of energy and angular momentum, which describe its location with..

Take distilled water in a trough. Boiled and cooled water can also be taken since it does not contain dissolved air. Invert a gas jar filled with oxygen, over it, as shown in the figure (Fig.13.9). After some time, the level of the water rises inside the gas jar indicating that..
