Fluid mechanics is the branch of physics concerned with the mechanics of fluids (liquids, gases, and plasmas) and the forces on them. [1]: 3 It has applications in a wide range of disciplines, including mechanical, aerospace, civil, chemical, and biomedical engineering, as well as geophysics, oceanography, meteorology, astrophysics, and biology.
The Education and Literacy Department is a key division of the Government of Sindh, Pakistan, responsible for overseeing the provincial's education system.Its primary role is to manage educational affairs within Sindh and coordinate with the Federal Government and donor agencies to promote education.
In this model the red fluid – initially on top, and afterwards below – represents a more dense fluid and the blue fluid represents one which is less dense. The Rayleigh–Taylor instability is another application of hydrodynamic stability and also occurs between two fluids but this time the densities of the fluids are different. [ 6 ]
Dayaram Jethamal Sindh Government Science College, [1] (Urdu: ڈی جے سندھ گورنمنٹ سائنس کالج) commonly known as DJ Science College, is a public community college that is affiliated with the Board of Intermediate Education Karachi and the University of Karachi — it is located near Burns Road in Karachi, Sindh, Pakistan.

A nanofluid is a fluid containing nanometer-sized particles, called nanoparticles. These fluids are engineered colloidal suspensions of nanoparticles in a base fluid. [1] [2] The nanoparticles used in nanofluids are typically made of metals, oxides, carbides, or carbon nanotubes. Common base fluids include water, ethylene glycol, [3] and oil.
Fluids may be classified by their compressibility: Compressible fluid: A fluid that causes volume reduction or density change when pressure is applied to the fluid or when the fluid becomes supersonic. Incompressible fluid: A fluid that does not vary in volume with changes in pressure or flow velocity (i.e., ρ=constant) such as water or oil.
These boards set their educational policy under the supervision of the provincial education ministry. [1] This list of education boards in Pakistan shows their year of establishment, jurisdictions (districts) and websites, arranged alphabetically.
The main body of students is admitted each year to Class 8. Until the academic year 1998–99, the college used to admit a small contingent of boys from the rural districts of Sindh to Class 7, to prepare them for competitive success with the new entry into Class 8. However, it was decided by the Board of Governors of the college to discontinue ...
