What is Inlet Capacity Calculator?

The Inlet Capacity Calculator is a handy tool that estimates an inlet’s capacity based on several factors, including orifice flow coefficient, opening area and allowable head. Equation Q = C * A * sqrt(2 * g * H) yields this result; with Q being the capacity, C representing orifice flow coefficient, A representing inlet opening area, g representing acceleration due to gravity and H representing allowable head.

The orifice flow coefficient is a non-dimensional parameter that takes into account the shape and size of an orifice as well as its fluid properties. It’s usually determined experimentally and may differ depending on the design of the orifice and used fluid. The inlet opening area refers to where fluid enters the inlet while allowable head refers to maximum head that the inlet can handle without overflowing.

Example:

Let’s assume that we have an inlet with an orifice flow coefficient of 0.67, an inlet opening area of 1 square meter, and an allowable head of 2 meters. To calculate the inlet capacity, we can use the formula as follows:

Q = C * A * sqrt(2 * g * H) = 0.67 * 1 * sqrt(2 * 9.81 * 2) = 3.30 m^3/2

Therefore, the inlet capacity is 3.30 m^3/2. This means that the inlet can handle a maximum flow rate of 3.30 cubic meters per square root of meters per second without overflowing.

Calculation Steps:

1. Obtain the orifice flow coefficient, inlet opening area, and allowable head for the inlet.
2. Determine the value of acceleration due to gravity (g), which is approximately 9.81 m/s^2.
3. Substitute the values into the formula Q = C * A * sqrt(2 * g * H).
4. Simplify the expression by multiplying the orifice flow coefficient, inlet opening area, and square root of 2gH.
5. Evaluate the expression using a calculator to obtain the inlet capacity.
6. Round the result to an appropriate number of significant figures and include the units of measurement.

The Inlet Capacity Calculator is an invaluable resource for engineers and designers who need to estimate the capacity of an inlet based on its physical characteristics. Utilizing this calculator, they can quickly determine the maximum flow rate that the inlet can handle without overflowing, helping them design more efficient drainage systems with greater effectiveness.
