Steam velocity through piping is the speed at which steam travels through a pipe. It's a crucial factor in designing steam systems because excessive velocity can cause several issues like erosion, water hammer, and increased energy consumption. The ideal steam velocity depends on various factors such as pipe size, pressure, temperature, and the type of steam application. Generally, steam velocities are kept within a certain range to ensure efficient and safe operation.
