Steam Velocity Calculator

Formula

The formula to calculate the Steam Velocity (Vs) is:

\[ Vs = \frac{QV}{FA} \]

Where:

\(Vs\) is the steam velocity (ft/s)
\(QV\) is the steam volume flow rate (ft³/s)
\(FA\) is the flow area (ft²)

What is Steam Velocity?

Steam velocity measures the linear speed of steam through an enclosed area. The steam velocity depends on the size of the flow, pressures, relative humidity, and temperatures. Understanding steam velocity is important for designing and optimizing steam systems to ensure efficient and safe operation.

Example Calculation

Let's assume the following values:

Steam Volume Flow Rate (QV) = 500 ft³/s
Flow Area (FA) = 20 ft²

Using the formula to calculate the Steam Velocity (Vs):

\[ Vs = \frac{QV}{FA} = \frac{500}{20} = 25 \text{ ft/s} \]

The Steam Velocity (Vs) is 25 ft/s.
