Equivalent Diameter for Triangular Pitch in Heat Exchanger Solution

STEP 0: Pre-Calculation Summary

Formula Used

Equivalent Diameter = (1.10/Pipe Outer Diameter)*((Tube Pitch^2)-0.917*(Pipe Outer Diameter^2))
D_e = (1.10/D_Outer)*((P_Tube^2)-0.917*(D_Outer^2))
This formula uses 3 Variables

Variables Used

Equivalent Diameter - (Measured in Meter) - Equivalent diameter represents a single characteristic length that takes into account the cross-sectional shape and flow path of a non-circular or irregularly shaped channel or duct.
Pipe Outer Diameter - (Measured in Meter) - Pipe Outer Diameter refers to the measurement of the outside or external diameter of a cylindrical pipe. It includes the pipe thickness into it.
Tube Pitch - (Measured in Meter) - Tube Pitch in a heat exchanger refers to the center-to-center spacing between adjacent tubes in a tube bundle of heat exchanger.

STEP 1: Convert Input(s) to Base Unit

Pipe Outer Diameter: 19 Millimeter --> 0.019 Meter (Check conversion here)
Tube Pitch: 23 Millimeter --> 0.023 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

D_e = (1.10/D_Outer)*((P_Tube^2)-0.917*(D_Outer^2)) --> (1.10/0.019)*((0.023^2)-0.917*(0.019^2))

Evaluating ... ...

D_e = 0.0114610157894737

STEP 3: Convert Result to Output's Unit

0.0114610157894737 Meter -->11.4610157894737 Millimeter (Check conversion here)

FINAL ANSWER

11.4610157894737 ≈ 11.46102 Millimeter <-- Equivalent Diameter

What is Shell and Tube heat exchanger?

A Shell and Tube Heat Exchanger is a common type of heat exchanger used in various industrial applications to transfer heat between two fluids. It consists of a large, cylindrical outer shell (usually made of metal) with multiple smaller tubes (also made of metal) running through it. The tubes are arranged in a bundle inside the shell and are typically oriented parallel to the shell's longitudinal axis.

What is Triangular Pitch?

triangular Pitch Pattern is the shape of accommodating the tubes in the shell and tube Heat Exchanger. This pattern is used when the fluid in tube side is corrosive/ fouling. Triangular Pattern Tube Pitch provides the Highest heat transfer Coefficient among all patterns available.

How to Calculate Equivalent Diameter for Triangular Pitch in Heat Exchanger?

Equivalent Diameter for Triangular Pitch in Heat Exchanger calculator uses Equivalent Diameter = (1.10/Pipe Outer Diameter)*((Tube Pitch^2)-0.917*(Pipe Outer Diameter^2)) to calculate the Equivalent Diameter, The Equivalent Diameter for Triangular Pitch in Heat Exchanger formula is defined when the tube arrangement is in triangular pattern in a shell and tube Heat exchanger. Equivalent Diameter is denoted by D_e symbol.

How to calculate Equivalent Diameter for Triangular Pitch in Heat Exchanger using this online calculator? To use this online calculator for Equivalent Diameter for Triangular Pitch in Heat Exchanger, enter Pipe Outer Diameter (D_Outer) & Tube Pitch (P_Tube) and hit the calculate button. Here is how the Equivalent Diameter for Triangular Pitch in Heat Exchanger calculation can be explained with given input values -> 11461.02 = (1.10/0.019)*((0.023^2)-0.917*(0.019^2)).
