QUICK METHOD FOR BOND WORK INDEXAPPROXIMATE VALUE
The Bond work index is a parameter which represents a measure of an ore resistance to grinding. Numerically, the work index represents the energy (kWh/sht) required to reduce the material of one short ton from a theoretically infinite feed size to size at which 80 percent of material passes through sieve with square aperture100

Solar is displacing Coal in India's electricity market
19/11/2020Global capital and corporates are increasingly fleeing stranded asset risks, as recent new coal power exit announcements by KEPCO, JERA and Mitsui Co highlight. The IEA predicts the levelised cost of energy (LCOE) of solar will be dramatically down at US$15/MWh (~Rs1.1/kWh) by 2040 from US$35/MWh (~Rs2.6/kWh) in 2019.

How to Calculate kWh (Kilowatt
To get the number of kWh, you just multiply the number of kW by the number of hours the appliance is used for. For example, a device rated at 1500 W that's on for 2.5 hours: 1500 1000 = 1.5. That's 1.5 kW. 1.5 x 2.5 = 3.75. So, a 1500 W appliance that's on for 2.5 hours uses 3.75 kWh. How do I calculate kW to kWh?
