CV_CHAR_QUICK_OP

Overview

Calculates the flow coefficient characteristic for a quick opening control valve.

Excel Usage

=CV_CHAR_QUICK_OP(opening)

• opening (float, required): Fractional opening of the valve [0-1].

Returns (float): Flow coefficient characteristic fraction [0-1].

Examples

Example 1: Zero opening

Inputs:

opening
0

Excel formula:

=CV_CHAR_QUICK_OP(0)

Expected output:

0

Example 2: Full opening

Inputs:

opening
1

Excel formula:

=CV_CHAR_QUICK_OP(1)

Expected output:

1

Example 3: Half opening

Inputs:

opening
0.5

Excel formula:

=CV_CHAR_QUICK_OP(0.5)

Expected output:

0.902547

Example 4: Quarter opening

Inputs:

opening
0.25

Excel formula:

=CV_CHAR_QUICK_OP(0.25)

Expected output:

0.788538
