खनन और खनिज उद्योगों में पर्यावरणीय स्थिरता विषय पर विशेषज्ञों का मंथन

खनन और खनिज उद्योगों में पर्यावरणीय स्थिरता  विषय पर विशेषज्ञों का मंथन पर्यावरणीय स्थिरता मानव समाज के निरन्तर अस्तित्व, समृद्धि और स्वास्थ्य के लिए मूलभूत शर्त है। हमारी न्यू जनरेशन को स्पीड और टेक्नोलॉजी पर ध्यान केंद्रित करना होगा ताकि भविष्य को सुनहरा बनाया जा सके। उक्त विचार मुख्य अतिथि श्री एमपी सिंह, प्रधान मुख्य अभियंता, केंद्रीय विद्युत प्राधिकरण विद्युत मंत्रालय भारत सरकार, नई दिल्ली ने व्यक्त किए श्री सिंह भूपाल नोबल्स स्नातकोत्तर महाविद्यालय में भूविज्ञान विभाग द्वारा "खनन और खनिज उद्योगों में पर्यावरणीय स्थिरता" विषय पर आयोजित दो दिवसीय राष्ट्रीय कॉन्फ्रेंस के समापन पर बोल रहे थे। दो दिवसीय राष्ट्रीय कान्फ्रेंस का भव्य समापन सम्मानित अतिथि प्रो विनोद अग्रवाल सदस्य, भारत सरकार नई दिल्ली स्थित MOEFCC की विशेषज्ञ मूल्यांकन समिति, (सि एण्ड टीपी) अपने उद्बोधन में कहा कि पर्यावरण स्थिरता सरकार और समाज दोनों की जिम्मेदारी है। वर्तमान में खनन उद्योग विभिन्न प्रावधानों एवं कानूनों के तहत कार्य कर रहा है ताकि पर्यावरण को सुरक्षित रखा जा सके। आयोजन सचिव डॉ. हेमंत सेन न...

Virial equation of state and Boyle temperature


    Ideal gas

  • An ideal gas is a gas which satisfy Boyles’ and Charles’ law for all the values of pressure, volume and temperature completely.
  • Equation of state of an ideal gas for 1 gm molecule or 1 mole is PV = RT.
  • In deriving this equation it was assumed that
  • The size of gaseous molecules are infinitely small, so they do not occupy any space.
  • There is no attractive or repulsive force between the gaseous molecules, so they have only kinetic energy, not potential energy.

  • Deviation from perfect gas equation

  • No gas is ideal or perfect, because no gas follow the ideal gas equation PV = RT at all conditions.
  • The gases which liquified easily show more deviation from the ideal gas equation.
  • For every gas there is a temperature at which the value of PV remain almost constant with increase in P and the value of PV increases at very high pressure. This particular temperature is known as Boyle temperature (TB).
  • Below TB, PV first decreases with increase in P, reaches to a minimum value and then increases with increase in P.
  • Above TB, the value of PV increases with increase in P from beginning.

    • Virial equation of state

  • PV = A + BP + CP2 + DP3 + ...

    • NOTE

  • The present lecture is a bilingual lecture, in which every step is explained in Hindi and in English language. Virial equation of state and Boyle temperature is very important in Thermodynamics. In the present lecture the Virial equation and Boyle temperature is explained in a well systematic way.

Electric field due to circular loop of charge | Electromagnetics

Electric field due to circular loop of charge Electric field The space around a charged particle in which another charge experience a force is known as electric field. The source of electric field is either a charge or a time varying magnetic field. If the value of electric field does not change with time, then it will be uniform electric field, otherwise it will be non-uniform electric field. Electric field due to circular loop of charge If λ is linear charge density, then the charge on d l dq = λ d l      ⇒     dq = (q / 2πa) d l Electric field at P due to charge dq Special cases When P lies at the centre of the loop i. e., r = 0, then E = 0 When P lies very far from the centre of the loop i. e., r >> a, then E = kq / r 2 In this case circular loop behaves as a point charge.

American Activity in Venezuela: A Simple Guide for Students

American activity in Venezuela is an important topic in international relations. It includes political involvement, economic decisions, oil interests, and humanitarian support. This blog explains the topic in simple terms for students. History of U.S.–Venezuela Relations For many years, the United States and Venezuela shared friendly relations. Venezuela was a major supplier of oil to the U.S., and many American companies invested in Venezuela’s oil industry. These strong economic ties helped both countries grow. Impact of Hugo Chávez on U.S.–Venezuela Relations In 1999, Hugo Chávez became the President of Venezuela. His socialist ideas and strong opposition to U.S. influence changed the relationship. He reduced the role of American companies and strengthened ties with countries that opposed U.S. policies. This marked the beginning of political tension. U.S. Political Involvement in Venezuela The United States claims that its actions in Venezuela are aimed at supporting democracy...

Thomson’s parabola method | EMFT and Relativity | Motion of charged particles in E and B fields

Thomson’s parabola method Positive ray analysis This method is used to find the charge to mass ratio. Thomson parabola method T = Discharge tube, the pressure of gas in this tube is kept 0.01 mm of Hg E = Capillary tube C = Cathode, which is perforated with an extremely small holes W = Water jacket, used to cool the cathode A and B = Metallic plates, the electric field is applied between these plates N and S = North and south poles of a heavy magnet K = Highly evacuated camera P = Photographic plate R = Liquid air trap, used to keep the pressure in K quite low Working To ensure the supply of the gas, a steady steam of the gas is allowed to pass through E and after circulating the tube, it is escaped through M. The positive ion produced in T move towards C. The ion which reaches C axially. pass through its fine hole in the form of narrow beam. After crossing C, the parallel beam of ions enters into the electric and magnetic...
