The welding procedure for P91 material involves preheating, maintaining interpass temperature, and post-weld heat treatment.
P91 material is a type of high-strength, low-alloy steel used in high-temperature applications.
The welding procedure for P91 material typically includes preheating the base metal to a specific temperature range.
Interpass temperature control is crucial to prevent cracking and maintain the mechanica...

GCV (Gross Calorific Value) of coal refers to the amount of heat released during combustion of a unit quantity of coal.
GCV varies depending on the type of coal, with anthracite having the highest GCV and lignite having the lowest.
Higher GCV coal is more energy efficient and produces less ash and pollutants when burned.
Examples of GCV values: Anthracite - 25-33 MJ/kg, Bituminous - 20-30 MJ/kg, Sub-bituminous - 15-24 MJ/

Scope of Renewable energy in India
Current is the flow of electric charge in a circuit.
Current is measured in Amperes (A).
It is the rate of flow of electric charge through a conductor.
Current flows from the positive terminal to the negative terminal in a circuit.
There are two types of current - direct current (DC) and alternating current (AC).
Conductors diameter can be calculated using the formula: diameter = sqrt((4 * area) / pi)
Calculate the area of the conductor (usually circular) using the formula: area = pi * (radius^2)
Determine the radius of the conductor
Use the formula: diameter = sqrt((4 * area) / pi) to calculate the diameter

The ratio of cement, sand, and aggregate in M20 concrete is 1:1.5:3.
The ratio of cement to sand to aggregate is 1:1.5:3 in M20 concrete.
For every 1 part of cement, 1.5 parts of sand and 3 parts of aggregate are used.
This ratio ensures the desired strength and workability of the concrete mix.
