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.

Full wave rectifier

A device which is used to convert alternating current (or voltage) into direct current (or voltage) is known as rectifier, and the process of converting a.c. into d.c. is known as rectification. There are two type of rectifier half wave rectifier and full wave rectifier. A rectifier which converts only half cycle of input a.c. into d.c. is known as half wave rectifier and a rectifier which converts complete cycle of input a.c. into d.c. is known as full wave rectifier. Here in this session we have discussed only about full wave rectifier, and a brief idea of half wave rectifier is also given here. In this lecture we have determined the average value of current, rms value of current, efficiency of full wave rectifier, ripple factor and also about the frequency component. Here we have explained everything in Hindi and in English language, so it is bilingual lecture. This topic is related to electronics and solid state physics.
