it's a narraw shaft drilled through rock like a well from where liquids or gases can be pumped up mechanically by a lever or by electrical pump
The types of mechanical work include static work, dynamic work, and intensive work. Static work refers to work done without motion, dynamic work involves movement, and intensive work focuses on the internal energy changes within a system.
Input work is the work done on a machine, while output work is the work done by the machine. Efficiency of a simple machine is calculated as the ratio of output work to input work. The efficiency of a simple machine is high when the output work is close to the input work, indicating that the machine is converting most of the input work into useful output work.
The formula that relates work and power is: Power = Work / Time. Power is the rate at which work is done, which is the amount of work done divided by the time it takes to do that work.
the work a machine does is the work output what it takes to do the work is the work input
The formula to find the work output of efficiency is: Work output = Efficiency x Input work. Efficiency is a ratio of output work to input work, so multiplying this ratio by the input work gives the work output.
borehole in Tagalog: pagbutas
As a noun, 'borehole' doesn't have an antonym.
There's a beetle in this borehole.
A borehole geophysical log is the science of recording and analysing measurements of physical properties made in wells or test holes. Borehole Geophysical logs provide a borehole record of the lithology, fractures, permeability, porosity and water quality.
Not 100% sure on the question whether it means surveying an existing borehole or assessing the viability of drilling a new one. If it's surveying an existing borehole for problems etc that is usually done via CCTV where a camera is lowered into the well. If it's assessing the viability of drilling a new borehole then that's called borehole prognosis and that is carried by a hydrogeologist who geology, hydrogeology, water quality, potential yield and borehole depth requirements.
The Kola Superdeep Borehole was closed due to a lack of funding and the challenges of drilling to extreme depths.
The Kola Superdeep Borehole was begun in 1970 and finished in 1992. It reached 12,262 meters deep. Work ceased due to the difficulties of drilling in extreme temperatures (~300 degrees Celsius) and lack of funding.
A deep borehole is drilled much deeper into the ground compared to a shallow borehole. Deep boreholes are typically used for extracting resources such as water, oil, or gas from deep underground reservoirs, while shallow boreholes are often used for environmental monitoring, water wells, or geotechnical purposes at shallower depths.
Drilled Hole: a deep hole drilled into the ground to obtain samples for geological study or to release or extract water or oil Usually narrow in width. Probably the most common type is a water borehole, which is where the borehole is used as a water well.

They are the same.
The construction of a borehole typically involves several key stages: Site Assessment: This initial stage includes evaluating the location for geological suitability and environmental impact. Drilling: Using specialized equipment, the borehole is drilled to the required depth, often using rotary or percussion drilling methods. Installation: Once the borehole is drilled, casing is installed to prevent collapse and contamination, followed by the installation of a well screen to filter water. Testing and Development: Finally, the borehole is developed and tested to assess water quality and yield, ensuring it meets the intended use.
