 The Entrance Length Number for Turbulent Flow computes the length based on the Reynolds Number.

INSTRUCTIONS: Enter the following:

• (Re)  Reynolds Number

Entrance Length Number (ELT): The calculator returns the length number.

The Math / Science

The Entrance length number correlation with the  Reynolds Number for turbulent flow can be expressed as:

    `ELT = 4.4 Re^(1/6)`

Where:

• ELT = Entrance length number
• Re = Reynolds Number
