How do you find the capacity of a reservoir from a contour map?
Untitled Document. The storage capacity of a reservoir is determined from contour map. The contour line indicating the full reservoir level (F.R.L) is drawn on the contour map. The area enclosed between successive contours are measured by planimeter (Figure 18.5).
What is reservoir volume?
The following terms are used in connection with the volume of reservoirs: Nominal Volume or Capacity is the total volume of all water held behind a dam at the maximum level possible. Initial or Design Volume refers to the possible volume within the reservoir after it first opens.
How do you calculate land volume?
The area of a square or rectangular garden is easy to calculate. Simply multiply the length by the width by the depth or use our simple volume calculator. Circular areas are also easy to calculate. Simply multiply 3.1415 (π) by the radius, by the radius again, by the depth or use our simple volume calculator.
Which is the largest artificial lake by volume?
Lake Kariba
Lake Kariba is the world’s largest man-made lake and reservoir by volume. It lies 1,300 kilometres (810 mi) upstream from the Indian Ocean, along the border between Zambia and Zimbabwe.
What is the largest reservoir for nitrogen?
the atmosphere
The largest reservoir of nitrogen is found in the atmosphere, mostly as nitrogen gas (N2). Nitrogen gas makes up 78% of the air we breathe. Most nitrogen enters ecosystems via certain kinds of bacteria in soil and plant roots that convert nitrogen gas into ammonia (NH3). This process is called nitrogen fixation.
How to calculate the volume and surface of a reservoir?
In this case, the result is in cubic meters, since we are working in International System of Units (S.I.): 11,834,796.1198 (equivalent to 11.835 cubic hectometers ). We also got the total flooded surface: 1110140.5082 square meters (equivalent to 111.014 hectares ).
How are pore volumes used in reservoir appraisal?
When detailed appraisal data become available, the reservoir regions and areas will of course be given separate values, but the same equation will be used to calculate regional pore volumes. The volume of reserves VR is the product of pore volume, hydrocarbon saturation Sh, and recovery factor RF.
How is the contour area of a hydrocarbon measured?
If a planimeter is not available, the contour area can be divided into small squares of known area. The number of squares is counted. The total area is the product of the number of squares and the area of each square. 2. Convert the measured area to a mapped area.
How is the volume of hydrocarbon reserves calculated?
The volume of reserves VR is the product of pore volume, hydrocarbon saturation Sh, and recovery factor RF. Writing pore volume as the product of porosity ϕ, area A, and net thickness h, VR is given by
