This can also occur due to poor heating of steam network before the steam enters into the system. Piping network remains cool and as soon as the hot steam...
Atmospheric air (A) is compressed in compressor and pressurized air (B) enters into the GT combustor where it mixes with fuel and undergoes combustion.
The...
These valves can be operated using either of AC (Alternating Current) or DC (Direct Current) electrical signals.
Following are a few types of solenoid...
Venturi meter is also based on Bernoulli's principle similar to orifice plate. But instead of sudden constriction caused by an orifice, venturi...
Heat transfer rate per unit area of the wall is calculated as,
Q/A = k × (T1 - T2)/L
Q/A = 0.3×(650-150)/0.3048 W/m2 = 492.13 W/m2
This figure multiplied by...
